ABSTRACT The present paper gives a short report on recent results obtained by
experimental and theoretical work on the short-wave radiation of the
sun which were published since the first survey given of this topie
(S*L. MANDELSHTAM, Uspekhi Fiz. Nauk, Vol 46, p, 145 (1952)). The author
further "gesta that experiments be carried out by mearis of arttficial
earth satellites.
The radiation of the photosphere: The authors describe the paper by H.
CLEARMAN'IAstrophys. J. Vol 117, p 29 (1953) as the most important in
this fie" Above all the presence of various elements in the sun is
discussed, something is also said on molecular bonds. According to the
authors' opinion this paper by Clearman does not contain any essentially
new results. Other papers (among them theoretical ones) are then dis-
cussed.
The radiation of the chrmosphere was investigated by the spectral ana-
lyals of light by means of spectrographs. Photoelectric receivers with
Card 1/4 separation of a narrow spectral region were also used. By special systems

the optical axis of the spectrograph could be oriented to the sun, Ythile
the rocket covered the upper part of its orbit. In this manner the re-
corded spectrum could be farther advanced into the short-wave region.
Various papers on this problem are discussed.
The radiation of the corona was investigated in earlier as well as in
more recent works by means of photoelectric receivers, i.e. photon coun-
ters which separate narrow spectral regions by filters. The papers on
this problem are discussed in short,
The variations of radiation and the experiments carried out @Z means of
artificial earS satellites; The results given in the preceding articles
indicate the existence O=Very considerable variations of intensity of
the line L a emitted by the chromosphere and of the roentgen region of
the spectrum emitted by the corona. These variationsare doubtlessly con-
nected with physical processes taking place in the chromosphere and in
the corona of the sun. These variations of the intensity of short-wave
ultraviolet ionizing radiation of the sun cause considerable perturba-
tions in the terrestrial atmosphore (disturbance of radio communication,
magnetic storms etc.). The attempt vras recently made to connect these
Card 2/4 variations with solar eruptions.

Jnvestigations of the Short-Wave Ultraviolet Radiation of the Sun
The international geophysical year just coincides with the 1.1 years'
period of maximum solar activity, which is very favorable for the in-
vestigations of the variations of the intensity of short-wave solar ra-
diation. Artificial earth satellites should be well suited for this pur-
pose, Experiments planned in the USA are mentioned. In the U.S.S.R. the
measurements of solar radiation will be begun in the roentgen region of
the spectrum. The individual spectral regions will be separated by fil-
ters. The radiation currents will be measured by a single receiver. The
block system of an apparatus for the recording of the roentgen region
of the solar spectruin is illustrated by a drawing. Multipliers of be-
ryllium bronze will be used as radiation receivers for secondary elec-
trons. In front of the receiver are placed filters consisting of alu-
minum, beryllium, and polyethylene filters of various thicknesses. The
calc4ated transmission curves of various filters are illustrated by a
diagram and discussed. Every other two filters are changed in series.
In the disk with the filters there are also normal holes through which
the radiation directly impinges on to the photocathode. The signals
(voltage pulses) coming from the receiver impinge on to a counting and
recording radiotechnical system. At the output of this system continous
Card 3/4 voltages develop proportional to the counting speed of the pulses. The

Investigations of the Short-Wave Ultraviolet Radiation of the Sun
following stage in the investigations with earth satellites consists
of the determination of the line spectra of the chromosphere and the
corona of the sun. (With 33 illustrations, 5 tables).

ABSTRACT: The course of the life of Gri,-Ior 3amuilovich Landaberg was
lacking spectacular events, as it often happens in the case of
eminent scientists, but the more brilbart wa3 his scientific
career. The development of spectral analysis in the Soviet
Union is closely connected with the name of Landsberg. Landsber_K
was born in V31ogda on January 22nd , 1890, he was the son of an
official of the State Forest Service. He commenced his studies
at the Mathematical-Physical Faculty of the Moscow University
in 1908, and he left it with an excellent diplome. He published
his first scientific paper on very hi.--h resistancesin 1-,-,15
Later on, he was called to the arms. From 1916 to 1Q@20 he lec-
tured at the Agricul--tural Inotitute in Omsk and after his re-
turn to Moscow fie became a collaborator at the Institute for
Card 1/3 Physics and Biophysics. 1923 he was appointed assistant and later

an lecturer at the Institute for Theoretical Physics of the Moscow
University. From 1q23 to 1931 he was professor at the Second
Moscow University, (which is now the Pedagogical Institute).
Landsberg's work was strongly influenced by Mandel'shtam in the
years from 1925. Numerous investigations of Rayleigh's scatter-
ing (releyevskoye rasoeyaniye) were conducted by Landsberg and
his students in these years. Landsberg and hiandel'shtam examined
theoretically the combination scat,eriDg and, in 1930, they dis-
covered t@a fine structure of the Rayleigh line (liniya Rayleigh).
They discovered the selective scattering light in 1931. 1932
Landaberg was appointed corresponding member af the Academy of
Science of the USSR. He recognized, above all others, the pos-
aiLbilities of spectral analysis for purposes of material exa-
mination, and he received the Stalin prize for investigations
dealing with the same subject. At the beginning of the war, in
1941, Landsberg supervised the erection of emer.-ency installa-
tion of the Physical Institute of the Academy of Science of the
USSR in Kazan'. 1946 he became an acting member of the Academy
of Science of the USSR. He was one of the organizers of the new
Physical-Technical Faculty of the Moscow Univer3ity. There are

ABSTRACT: This speech was made on the occasion of the opening of the
XI. All-Union Congress on Spectroscopy, which took place imme-
diately after the October festivities (during the first days of
November 1957) at Moscow. The author mentions that under Soviet
rule important discoveries were made in this field in the USSR,
above all in the field of atomic and molecular spectroscopy, by
Vavilov and Cherenkov. Further, the works by D.S.Rozhdestvenskiy,
S.I.Vavilov, G.S.Igmdsberg, V.A.Fok, A.N.Terenin and
V.N.Kondrat'yev, which deal with this field, are mentioned. The
author further points out that applied spectroscopy is particu-
lar2y well developed in the USSR, and that it is being used in
various mys for research work and production control. The
author spoke a few words in connection with the decease of
G.S.Landsberg, Member, Academy of Sciences, USSR and former head of
Card 113 the coumission for spectroscopy, which took piace Inis year.

SOV/48-22-6-i/28
The author further telIz that th,3 last congress on spectroscopy,
which took place at Llvov was attended by 1600 delegates, 910
that 300 lectures were delivered. The excessive number of dele-
gates and the great number of subjects to be dealt with by
lectures were disadvantages which caused the organisers of the
congress to convene such meetings every year, but, on4 for one
particular field of spectroscopy. Thus, it is intended this year
to deal only with the physiml problems of spectroscopy, and that
problems of applied spectroscopy will form the sole subject of
the XII. meeting. The author is, however, of the opinion, that
recently a "dangerous tendencyl, has been developing in the USSR
with a view of forming two graaW of "spectroscopists": The
"atomists" and the "molec-alists". For the convenience of the
delegates it was decided that on forenoovz lectures of a general
character will be held, while speoia-I leotureB will figure on
the afterroon program. Finally, the author stresses the impor-
tance of maintaining contact with other countries, and he
mentions the names of foreign scientists who attended the congress

ABSTRACT: The investigation of the breadth and shape of spectral lines dn,"
not characterize the excitation of atoms with sufficient accumoy,
and therefore an investigation of the breadth and the displacement
of the lines is more advantageous for determining the causes of
these phenomena. The principal cause of the broadening and dis-
placement of spectral lines in a highly ionized plasma is its in-
teraction with charged particles. For lines with quadratic Stark
effect the impact theory of broadening results in the following
expressions for the brea4th of lines and their displacement:

the broadening of the lines form a Weisskopf radius that is too
small. The field formed by the electrons turns out to be so
strong on this occasion that the Stark effect ceases to be
quadratic and goes over to linearity. There is no reason to be-
lieve that the field changes slowly and is quasistatic as is
alleged by a well-known theory. The problem is still being dis-
cussed. There are i table and 3 references, 2 of which ara Sovist.

ABSTRACT: Vapour temperatLires in a spark are usually assumed to be equal to electron
temperatures of atoms and ions of the vapour. Electron temperature can
be determined from the relative Intensity of two or more spectral lines,
provided atoms are distributed in excited levels according to Boltunann's
lam. Earlier measurements (Rags 2. 20) yielded valuaa -10 OOOOK for
temperatures of electrode vapours in electric sparks; these values refer
to colder (crater) parts of vapour clouds ( tlflameG"). The Fresent paper
discuss as deter"ination of temperatures in hotter parts of vapour
clouds. Al III, Sn IV and SI IV lines were used (Table 1). Aluminium,
tin and silicon were used because their atoms have sufficiently high
ionization and excitation pot,:mtials to allow determination of temperatures
above 10 OOOOK. A glass spectrograph ISP-51 -was used for Al III lines
(visible region) and a quartz spectrograph ISP-22 was used for Sn IV and
Si IV lines (ultraviolet region). The apparatus used is shown in Fig 1.
The imge of a spark Sl vas focused on a spectrograph slit via

mirror M10 The latter wan rotated at 1-3 MIR/se c producing a time
scan (display) of the spark on a recording film in the spectrograph.
The time resolution of the spark spectra ranged from NO.04 to 0.1 lisec.
Sparks wore synchronized with rotation of MI by means of a device, shown
at the bottom of Fig 1, which ensured tK%t a sparV. at Sl was produced
when the image of 31 was focused at the apectrograph slit. The spark
discharge circuit parameters were: C = 0.01-1 IS, L = 2-3000 IiH. The
voltage across the spark gap Sl was 15 1cV and the distance between
electrodes was 2.5 mm. A record of a spectrum obtrtined between tin
electrodes is shown in Fig 21 it contains Sn IV, Sn 1, 11 11 and 0 11 lines.
The results are given in Tables 2-6. Table 2 refers to sparks between
tin electrodes (Sn IV lines). The results of Table 3 (Sn IV lines) were
obtained with one tin and one copper electrode. Table 4 gives temperatures
deduced from Sn IV and N 11 lines - Table 5 gives the results obtained
vith one aluminium or l0y@-Al bronze electrode (Al III lines). Table 6
gives temperatures deduced from experiments with "silumin" electrodes
containing 10% Si (Si IV lines). The temperatures deduced from Sn 1V
lines were -26 OOOOK, from Al III lines they were 30 OOOOK and from
Card 2/3 Si IV lines they -were 35 OOOOK. BorAuse of high scatter of the result3

it was impossible to say whether the differences between these three
sotq of temperatures were due to a definitue cause or accidental. Since
the spark-channel temperature, deduced from N II and N III lines, is
-35 OOOOK, the results obtained suggest that tin, all=inium and silicon
vapours were heated and excited in the spark channel itself. Acknowladg-
ments are made to L.P. tialyavkin and V.K. Bardin for their help in
experimental viorV. There are 3 figures, 6 tables and 13 references ,

The authors studied chano-as in the intensities of the lines in the
flame soectra of sodium and strontium when the forul of the compound used
to introduce the element vas altered and the changes which occurred on
introduction of compounds of other elements. To find the reasons for
these changes it is necessary to investigate the vkriations produced
in the density of free sodium or strontium atoins in the flame and the
variations in zhe conditions of excitation of these atoms. rho method of
anomalous discersion was used to ..@easure the Consities of atoms in the
flame. The apparatus used is shovrn schematically in Fig la; it is
based on D.S. Rozhdostvanskiyls interfarometer. To measure the densities
of atoms at v@-rious distances from the axis of ar, acetylene flame
(1 in Fig la) the interference fringes were localized at the contra of
the flame parallel to its axis. By means of three plane mirrors 2, 3, 4
and a lens 5,the flame and the interference fringes were projected on to

spectrograph ISP-51 was used. Solutions of the compounds amploye'd 7?.nre
injected into the flame by moans of an atomizer of the usual type. The
f1a.me diameter was 11 mm when Na, K or JAg were introduced into It,
9 ian for Li and 7 mm when Sr, Ca and Ba were used. The densities of
atoms were measured at a height of 15 mm above the blue part of tkv@ flame.
The experiment consisted of aleasuring the displacement of the int,4rfaranc6

across the flame by measuring the displacement of the interference
fringes at various distances from the centre of the flame. The aut '-:orc
recorded also photographically the intensities of the atomic lines and
they measured the flame temperature (using self-reversal of the lines).
First the authors studied the effect of the comoound which -.,jas used to

SrC12 and Sr(NO3)2. Displacement of the central interference fringe
was meAsured at distances of 1.5 and 2.6 1 from a sodium line at 5890
and at a distance of 0.52 A from a strontium line at 4607 A. Secondly
the affect Of MgC12, GaC12, SrC12 and BaCl.? on the density of sodium
atoms in the flame and the of fact of NaCl ari CaG12 on the density of
strontium atoms In the flame were Investigated. The authors measured
the displacement of the central interference rinc, at a distance of
1.3 1 from a sodium line at 5890 A and at a distance of 0.52 A from a
strontium line at 4607 A. The results (Figs 2-7) show that the changes
in the intensities of sodium and strontium lines,under conditions
discussed above, are due to simultaneous effect of two factors -
(1) a change in the free atom density in the flame due to a change in
the rate of supply of the solution and (2) a change in the conditions
of excitation due to a change in the flame temperature. This conclusion
is confirmed by theoretical calculations. There are 8 figures and
16 references, 5 of which are Soviet, 5 English, I German, I Dutch,

TITLE: Widening and Shift of Spectral Lines in the Plasma of Gas Dis-
charge
PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheskaya, 1959,
Vol 23, Nr 8, PP 1017-1020 (USSR)
ABSTRACT: In the present paper the widening of spectral lines with
quadratic Stark effect due to charged particles is investi-
gated. The equations (1) for the width and shift of the lines
are described. To compare theory with experimental results, the
dependence of width and shift on the constant of the quadratic
Stark effect and the ratio of width to shift are investigated.
The results show remarkable disagreement with the theory by
Weisskopf and Lindholm. Analysis of this disagreement resulted
in the development of an unsteady theory of the widening of
lines. According to the assumptions of the theory, a smaller
effect of the collision of electrons with atoms as well as in-
elastic collision of electrons with atoms are taken into ac-
count. For this theory, the nonuimensional parameter 0 is given
Card 1/2 by formula (2), which characterizes the width and shift of

SOV/48-23-8-18/25
Widening and Shift of Spectral Lines in the Plasma of Gas Discharge
lines. The ratio of width to shift depends on this parameter.
Figure 1 shows a comparison of theoretical values - calculated
by the unsteady theory - to experimental results. Good agree-
ment could be obtained. It was found that this theory permits
the determination of electron density from the width and shift
of lines. Table 4 compares electron densities calculated by
the steady and unsteady method. There are 1 figure, 4 tables,
and 2 references, 1 of which is Soviet.

TITLE: On the Short-wave Radiation of a Vacuum Spark
PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959,
Vol 37, Nr 20), PP 349-354 (USSR)
ABSTRACT: The spectra of the highly ionized atoms in a spark discharge are
in the ultraviolet range and in the range of soft X-ray radia-
tion; it was investigated down to 6 1 (Ref 1). In this case the
excitation energy amounts to 2000 ev. In the present paper the
authors give results obtained from investigating these spectra
within the range ),< 6 1, as well as an evaluation of the dis-
charge temperatures by means of a spectroscopic method. (Anal-
ogous temperature measurements have already been carried out by
Aki;aov and Malkov (Ref 2).) The measuring method is first brief-
ly described (iron electrode - one plate and one cylinder, dis-
tance 4 mm; initial pressure in the discharge chamber 1.10-5= Hg;

ray oscillograph. Total sensitivity of the FEU: 10 a/lumen;
filter dimensions: thickness 0.25 mm, diameter 18 mm; scintil-
lators: tetraphenyl-butadiene in polystyrene and CsI(Tl),
5 mm thick . The results are given in form of characteristic
oscillograme. Three series of measurements were carried out
under various conditions and by using the two above-mentioned
scintillators, and the latter are described in detail. The sec-
ond part of the paper deals with temperature evaluation. The
value obtained for electron temperature in the case of a spark
discharge in a vacuum was found to amount to 2.1o5 OK. These
evaluations agree with measurements. Figure 5 shows the temper-
ature dependence of the intensity of the lines of multiple
charged ions for an electron concentration ne - 10 18 electron/GM3;
the curves from Al V to Al X are given. The Position of the
curves shows to what extent temperature evaluation depends on
ionization - the curves shift with increasing ionization towards
higher temperatures; to the here mentioned temperature of

TEXT: This is the first of 3 investigations on X-radiation
in the range below 10 R carried out by research rockets and the
2nd and 3rd Sputniks. Provisional results of these measurements
were set forth in brief in an earlier study. Experimental
method: The measurements described in the present article were
carried out during the flight of 2 research rockets. The urime
object of the measurements was to accumulate experimental data
and to develop a method for subsequent measurements by means of

earth-satellites. As detectors, photon counters were used, as
these are more sensitive in the spectral range --@ 10 R than
vacuum photomultipliers, The sensor unit was placed on the in-
strument container which turned automatically towards the sun.
Special precautions were taken to ensure that no corpuscular
radiation should interfere with the measurements. In the first
launching, the sensor unit incorporated 2 similar counters
directed towards the sun; one of the counters had a inagnetic
shield, and the other had none, In the second launching, both
counters hag magnetic shields.. but the second counter was at an
angle of 15 towards the sun, recording non-solar radiation only,
Standard counters of type C 5 T 9 @SBT-9) viere used, The charac-
teristics of the counters are described. The cojn6ing rate @vas
calculated from the telemetered data, The 2 rockets were
launched on July 21, 1959, in the morning and evening respective-
ly. On that day, the solar activity was intense, Results: A

A considerable X-ray flow was recorded from altitudes of 95 km
up. Owing to the stability of orientation of the container Y/ith
respect to the sun, it was unnecessary to make allowance for the
angular dependence of counter efficiency. From the counting-
rate data, the energy distribution and the magnitude of the
energy flux outside the atmosphere were calculated. The data
processing was based on the expression m inci @__ Mvert (z)
where mincl is the mass of an inclined air-column of 1 CM2
cross-section lying between the apparatus and the sun, m vert-_
the mass of a vertical column e@ual to -the atmospheric pressure
at the given altitude, and (@ Z) is determined by the zenith
angle of the sun z, A figure shows the counting rate as a
function of mincl* Assuming the spectral region under investi-
gation to be continuous, it is possible to construct the photon-
distribution curve by means of the counting-rate curves, the mass

coefficients of absorption of air, and the spectral-sensitivity
curve of the counters, A figure shows the photon-distribution
curves as a function of wavelength. The energy distribution in
the morning and evening launchings was found to differ by a fac-
tor of 3. It is difficult to ascertain whether this difference
is real. The main source for the continuous radiation is elec-
tron bremostrahlung in the field of hydrogen and helium ions,
The obtained electron temperature considerably exceeded the
value of T e,--1 + 3 x 10 6 oK obtained in subsequent inveat:Lga--
tions by space-ships, A comparison of measurements condiicted by
Friedman (in 1953) during a minimum-period of solar activity
with the authors' measurements (in December 1960, by space-ship)
after a maximum-phase showed that the temperature and intensity
of radiation are greatiy dependent on the phase of the sun cycle,,
As the above-described rocket investigations were carried out
for very low positions of the sun above the horizon (in contra-

measurements are required. In ensuing articles, the results of
measurements carried out on the 2nd and 3rd Sputnike will be

TEXT: In a previous paper @Ref.l: Iskusstvennyye sputniki
Zemli, no.10, Izd-vo AN SSSR, 1961, p.12) the authors reported
MGasurements of the intensity of solar X-ray emission below 10
which were carried out with the aid of geophysical rockets. In
the present paper they report the corresponding results obtained
with the second and third Soviet spaceships on August 19-20 and
December 1-2, 1960. The aim of the measurements was to investi-
gate the intensity over an extended period of time(of the order
of a day or twol. Preliminary results have been given by the
authors in another paper (Ref.2: Dokl. AN SSSR, 14o, 1058, 1961).
The second spaceship carried six end-window photon counters
(15 m@&Lcm2 beryllium foils) with an oxygen-neon quenching mixture.

These counters were developed under the direction of 1. A. Prager
and S. M_ Perellman. The counters had a sensitivity of between
0.1 and 0.2 pulses/photon in the wavelength range 3-7.5 A. The
counters were mounted so that their axes were oriented along six
directions at equal angles to each other' the field of view of
each counter was 450. The telemetric record showing the counting
rate as a function of time is reproduced. It is estimated that
the flux of radiation in the range 2-10 A, which was recorded
durin the flare of August 19 (15 hr 33 min) was of the order of
-5 -2 -2 -1
7-10 - 1.5-10 erg cm sec The apparatus mounted on the
third spaceship was somewhat modified. Three types of probes were
employed so that tbp solar radiation below 10 4 could be
continuously monitoredtogether with interference due to radiation-
belt particles. The main detectors were two parallel-connected
C6 T-q (SBT-9) counters with mica windows (1.6 nig cm-2) and
located in a lead screen 1 mm thick. The counters were supplied
by solar batteries. In addition, there were two "control-
counters" which were mounted at right angles to the direction of
the sun. A tantalum plate was placed in front of the counter

windows and served as a target for the radiation-belt particles.
The counters were practically insensitive to solar X-ray radiation.
A third pair of counters was mounted on the outersurface of the
third spaceship. These counters were similar to those carried
by the second spaceship. The aim was to estimate the spectral
energy distribution by comparing the indications of the beryllium
and the mica counters. The telemetric record obtained with t
aid of the third spaceship is reproduced. It 4 is estimated t@at
the flux of radiation below 10 A was 2.5 .10- erg cm-2 sec-
Moreover, the intensity of radiation in this spectral region
remained constant within +20% during the observations. This was
due to the fact that on December 1-2, 1960 the sun was very
quiet and there was only one flare (importance 1+). The question
of the flux and the energy of the particles recorded in these
experiments is being examined at the present time. There are
10 figures and 2 tables.
