TEXTs A mechanism of the separation of a fragment from the nucleus in
the process of a nucleonic cascade is suggested. The nucleus is
assumed to,be structured and to contair nucleon groups connected with
th-, nuclear residue by few nucleons. In the nucleonic cascade these
binding nucleons can be knocked out, and the fragment is-emitted. The
probability of fragment separation from the nucleus is given by

TEXT: S. I. Vavilov made an important contribution to the interpretation
of the radiation of fast charged particles, which was discovered about
thirty years ago (P. A. Cherenkov, Dokl. AN SSSR, 2, 451 (1934);
S. I. Vavilov, Dokl. AV SSSR, 2, 457 (1934)). A ~Thotograph taken by
V~ P. Zrelov on a 660-Mev prot_o~ beam at OIYaI, Dubna, shows a ring
produced by a conical proton beam on the photoemulsion. Because of the
energy threshold resulting from 0> I/n, it takes extremely fast particle
to emit this Cherenkov radiation. The aperture angle of the radiation
cone widens with increasing particle velocity and reaches a maximum at

P = I/n, the above angle of aperture is vanishing, and no Cherenkov
radiation is emitted any longer. The extremely sensitive photomultipliers
available (the entire apparatus consists of a transparent medium in solid,
liquid, or gaseous state, an optical condensor, a photomultiplier, and an
electronic circuit) can be used for measuring even very small amounts of
light emitted from Cherenkov partioles. A counter for particles moving at
velocities greater than that of light is able to record only particles with
a definite minimum energy, moving toward the photomultiplier. Such counters
have a very high time resolution. In recent years, they have been used at
the 260-Mev synchrotron of MAN for studying the pr6duction of neutral pions
by photons. L. V. Kurnosova et al. (Sb. Iskusstvennyye sputniki Zemli,
vyp. 5, Izd. AN SSSR, 1960) studied the nuclear component of cosmic
radiation, especially its composition as a function of Z, using data from
the Cherenkov threshold counters of Lunik II. Valuable results were found
for the flux of cosmic particles for different Z in the energy range of
1.3 Bev/nucleon. The distinct directivity of the Cherenkov radiation
permits the selection of particles according to their velocity. The
usability of such counters was confirmed in the discovery of the antiproton.
Difficult though it is, also the energy of an individual particle moving at

a velocity greater than that of light can be determined from the
Cherenkov radiation. Considering that the refractive index can be changed
by a simple change of the gas pressure in a counter adjusted to an angle 9,
the mass distribution of beam.particles with equal momentum is easy to
determine. The production of a sufficiently intense light flash in the
beam requires a counter of 2.5 m length and 3 t weight and a fairly high
pressure in it. There are 5 figures and 7 references: 5 Soviet and
2 non-Soviet. The two references to English-language publications read

ABSTRACT: The accuracy of the optical and counting methods of
determining the concentration of an aerozole are
discussed. It is shown on an example of coal dust that
the determination of the weight contentration of
particles by the optical method is imore accurate than
the counting method (the maximum error + 15-45% as
against + 35-60%). However, both methois are more
accurate when only finer fractions are measured. The
correlation between the counting and optical methods,
i.e. the correlation between the specific number of
particles per mg of a Irozole (a) and specific surface
area of particles (Cm /mg - P) Is shown in Fig I and the
dependence of dispersiometric characteristics (a and P)

the particle mass, g is the gravitational acceleration. cX is
the "impedance coefficient" of the body and F is the force on
the body. Thus, in order to obtain v and N it is necessary
to measure F and dn/dt and to know c These quantities were
in fact measured with the apparatus shown in Fig.1 (I - chamber,

deflection of the trap 9 when the beam is let into th 'e chamber.
This is done by reflecting a beam of light off the mirror 11. In
order to reduce back-flow. there is an escape valve 6. To ensure
that c x = 2 (inelastic collisions). the trap 9 consists of a
sequence of thin metal dines containing apertures at their c*ntres

determining the rate at which the chamber 1 (whose volume is
known) is filled trith the gas and this is done by means of an
ionization manometer; The device has been used with argon,

ABSTRACT: In many investigations of synthesizing geranil chloride in
a good yield special attention was paid to the binding of
the 1 chloro-3-mothylbutene-2 to isoprene. Its production
,offered good prospects to the perfume- and vitamin industry.
This was the reason for many laboratories, such as the
authorls~, to investigate the reaction of the diene hydrocarbons
with their hydrochlorides in order to learn on which condi-

the character of the telomerization depends on the nature
of the catalyst: tin chloride promotes the formation of the
higher telomers besides geranil chloride, tin chloride that

and zinc chloride catalysts the yield of geranU chloride
depends first of all on the depth of the conversion, and
that with the same depth of conversion secured it does not
depend on the nature of the catalyst, the nature of the
halogen derivatives, the temperature, the ratio of reagents,

to the conclusion that on telomerizatibn of isoprene with its
hydrochloride two groups of catalysts have to be distinguished:
The catalysts of the first group (SnCl 41 TiCl 47 Fecl 3) yield
the highest telomers. The catalysts of the second group (ZnCl 29
Zn(BF 4)2 , BiBr 3) only lead to the stage of the formation of
terpene chlorides where the reaction stops. The cause of this
stop is, as has been already found previously, the partial
cyclization of the geranyl chloride into the terpenyl chloride.
Therefore the content of geranyl chloride in the terpene fraction
of the telomer is far less than vilien using catalysts of the first.

not affect its character. There are 1 table and 1 Soviet refer-

TITLE: va-Ma-M Kethods of Calculating Short-Wave

PMODICAL: Blektroavyazl, 1959,, Nr 10, pp-23-29 (USSR)
ABSTR&M In this article calculated field strengths for short-wave
radjA-linkdWe compared with experimentally m4sured
results, In the Soviet Union, four methods of calculation
are used: Kosikov's method (Ref 1), the method of the CRPL
of the American Bureau of Standards,, (Ref 2),
Kazantsev's method (Ref 3), and Robert's method (Ref 4).
The article deals mainly with the first three methods.
Because these make different assumptions, their results
do not agree and the extent of their differences
depends on the particular conditions of the problem. To
decide which is the most correct method, approximately
2000 monthly-median values of field strength were
obtained from about 30,000 separate measurements on
medium-latitude, radio-links at different times and at
different frequencies. Despite the large amount of
experimental data, it was nevertheless insufficient for

cycle. The experimental conditions are described: the
results apply to radio-links the great circle arcs of
which do not go higher than L to 640 northern latitude
in the Eastern hemisp#ere; the measured results were all
referred to a transmitted power of 1 kW9 the necessary
data for this reduction being"obtained from the
operational charts of the transmitting stations. Details
of the method of selecting the measurement periods and
of processing the experimental data are given. From the
total number of measurements, about 1000 median values
refer to the period of minimum solar activity (1953 to
1954) and were obtained on 9 radia-links of lengths
3000 to 7000 km, the majority of the measurements being
in the 10 to 20 Mc/s, band. The remaining 1000 median
values relate to the period of maximum solar activity
(1956 to 1957) and were obtained on 8 radio-links of
lengths 5000 to 11000 km at frequencies 5 to 20 Me/e,
The difference between the calculated and measured values
was evaluated as follows: the ratio of the calculated
value E and the measured value E of the median values

each frequency and for specific times of the day.. This
ratio is called the calculation error. The results are
tabulated in Table 1. in which the results are divided
-into two groups,.according to the degree of solar activity.
These groups are further divided into three parts; day,
dusk and night. It was found that the calculation error
for the day-field with maximum solar activity increases
with reduction in frequency. During the period of minimum
solar activity, when the absorption coefficient is low,
the calculation error in the 10 to 20 Mc/s band-has zko
clear correlation for frequency. The results show that
the error depends on the solar activity- being less during
periods of maximum solar activity. The calculation errors
for the night-fields show a different pattern. The
results indirectly support the assumption that the field
level is unaffected by the solar activity cycle. The
frequency-correlation assumptions made in the CRPL and
Kosikov methods are not justified by the measured results,
which showed that there is considerable frequency-
dependence and often the field strength increases with
Card 3/4 decrease of frequency. It is further concluded that the

calculation error does not show any clear correlation
with the season and it does not vary much with path OP-111,
length. Over path lengths of 3000 to 11000 km, the
methods of Nosikovq Kazantsev and Roberts are better
than the OPRL method and over the frequency range
10 to 20 Mc/s. their calculation error does not usually
exceed f 10 db and there is often no error. The simplest
method from the point of-view of calculation is
lazantsev's method. ", Meyerao&,,_T.. U. TAIrbanhava

Perseids (Rof.1). ' Zatharov round that the minimum measured value
Occurred three days after the maximum of the Perseid stream but
that the time depended*on the wavelength used (Ref.2).
Giovanelli (Ref.3) calculated the sizwand number of the particles
responsible, and information on those data has also been obtained
from radar (Ref.5) and rocifet (Ref.6) observations as well as from
,.collection of magnetic material (Ref.7) and work on the zodiacal
light. It seems likely that the dust in the troposphere derives

from the Earth, whereas that in the stratosphere is of interplanetwy
rigin. An equation in derived giving the distribution of dust
:
ith height in the presence of convection (Eq.(7)) . This formula
is considerably more complicated than the exponential expression
which holds in the absence of convection. A lower limit for the
number of dust particles in the stratosphere is then derived,
assuming that tropospheric convection does not extend into the
stratosphere. It is found that the mass of particles entering the
Earth's atmosphere is 5.5 x 10-15 gM/CM2 sect The authors next
consider the effect of the dust content on the solar halo and, in
this connection derive an equation to represent it, Fig,l is
obtained from this equation and consists of a plot of halo
brightness against height for various wavelengths. (The
observations were made from an aircraft.) The atmospheric
transmission coefficient is closely connected with halo brightness,
but effects in the lower atmosphere can be sufficiently large to
blot out effects in the upper atmosphere. From data obtained in

the period 1933 to 1955, it is found that the intensity of solar
radiation seems to oscillate with'& period of 5 to 7 days as
well as having mini" during meteor showers. It is shown that
there is a linear correlation between the intensity of short
wavelength solar radiation and the'number of meteors per hour
found by radar observations. A correlation was also found
between oscillations in solar radiation and radio-echo
observations, although maxima and minim of the two'curves were
displaced. The authors finally cal6ulate the ratio of the
intensity of light scattered by meteoritic dust to that scattered
by air molecules at varying'heights. The results are shown in
FIS.6 for different angles of scattering and different elapsed
times after the initial influx of the particle stream. It was
found that the ratio had a constant maximum At 87 ka for all
angles of scattering near the level of the noctilueent clouds
(Fis-7). There are 7 figures, I table and 20 references:
