--kBSTRACTi The present paper intends to investigate the rules governing the
formation of a static load occurring on the occasion of the separ-,
ation of two bodies which had hitherto been in contact with each
other. For this purpose measures were taken in order, if possible,
to eliminate all elements of dynamic character. For this purpose
a special apparatus was constructed. Summary of results:
1) When breaking contact a transfer of electrons takes place, the
basic process being the tunnel effect. The amount of charges remain-
ing on the separating surfaces depends on the velocity of the
breaking of contact.
2) The dependence of charges measured on the occasion of the break-
ing of contact between two metals upon the contact difference of
these metals is represented by a straight line.
3) If a semiconductor and a metal serve as a separated pair, the
amount of the charge to be measured is a function of the contact
difference of the potentials of the investigated substnaces, of
the concentration of the free current carriers of the semiconductor
and its dielectric constant. If both of the latter quantities

are constant, the dependence mentioned under 2) is a straight line
also in this case.
4) In the case of semiconductors with a relatively low volume
concentration of current carriers (garmanium, tellurium), it is
possible, by utilization of the dependence of the charges (which
are measured when contact is broken) on the concentration of the
free current carriers to determine a difference between the concen-
tration of the carriers near the surface and those inside the body.
The relative change of charge concentration on the surface when
passing from one point of the sample to another can be determined,,

For purposes of control the same germanium sample was irradiated with a

Thus, the 4 keV cesium ions penetrateLinto germanium to a depth of about

assumed that in the case under review the formation of
thermal acceptors takes place like a certain spatial
relaxation-process whose equilibrium state is at the end
determined by the conditions existing in the sample
already before the Veginning of the process. It is assumed
that these acceptors which are contained 4~n the initial
sample in a bound form are converted to a state of action
only as a consequence of a heat-treatment. The evaluation
of the activation-energy yields about 2,45 eV and the
evaluation of the recombination-section of the unreal
(minor?) carriers on the thermal acceptors about 5-io-17 qcm.

AZSTRACT., Reference is made to the earlier reports given by the authors (referen=
ces 1 and 2). An evaluation of the depth of penetration of medium-energy
ions in germanium at the direct expense of their kinetic energy is given
here. It became evident that when a function of the following shape

lattice-atoms (as it was assumed in calculations of a similar kind in re=
ferences 3 and 4) it is possible, with the taking into accotmt of the mul=
tiple collisions according to the Monte-Carlo method, to obtain a curve.
This curve represents the dependence of the relative number of ions which
have attained the respective depth over the depth itself. In contrast to
the widely spread opinion it is shown here that the depth of penetration

TITLEz A Study of Plasmon Spectra

TEXT: The authors wanted to work out a method of determining the plasmon
spectra, when assuming for energy values to be absolutely accurate on
three points. In a previous paper (Ref. 7) they had described an electro-
static energy analyzer, which is specially suited for measuring the energy
on plasmons. The simplest variant of this instrument (single-stage device
with homogeneous field) was made use of here. The plasmon energy was
determined in aluminum. Fig. 3 shows the spectrum, taken by oscilloscope,
of the characteristic losses in aluminum. The plasmon energy was deter-
mined from the line distance; it lies with a probability of 0.9 at
*nO= 15-18 t 0.06 ev. The values found by other authors range between
14.7 and 15.8 ev (Refs..10-19) and are compiled in a table. If the value

whereas, if the oscillations of polarization of ion trunks are considered,
one obtains 15-48 ev, which comes very close to the value determined
experimentally. The mean free path of a 14-5-kev electron in Al for the
production of a plasmon amounts to 200-650 A. A. Ya. Vyatskin is

TEXT- The effect produced by ion bombardment upon the surface properties

all, nothing is known about the effect produced by the type of ions, i. e.,
the most contradictory opinions have been expressed (Refs. 2 and 4). A

the effect of bombardment does not depend on the type of ions, the effect

papers uniquely proved that different effects are produced by different
ions. The present paper deals with a study of the volt-ampere
characteristics of W-Ge and W-Si point contacts in the irradiation with
atomic oxygen ions and molecular nitrogen ions of 5 and 10 kev. The
experimental conditions were chosen in such a manner that an answer to
the especially interesting questions (change in carrier mobility, carrier
concentration of the scattering centers) could be expected. Theoretical
considerations in this direction are discussed in detail; they led to the
conclusion that an investigation of the volt-ampere characteristics of
point contacts finvestigation of direct and reverse currents and of the
rectification constant between semiconductor and metal may supply the
required information in a bombardment with ions of 5-10 kev. The
radiation dose was varied within the range of from loll-lo15 ions/OM2.
The experiments were carried out by means of the mass separator described
in Ref. 3. The ion source was gaseous (impact ionization); the
irradiated specimens were n-type Ge and Si single crystals with a
concentration ratio of the carriers of n/no - 1.10 9 and 7,10- ,
respectively. The individual measurements were repeated with due

results were evaluated according to M, 0. Kornfelld* Measurements are
illustrated in Figs, 3 and 4. Fig. 3 shows the ratio of the rectification
constant after irradiation to its value before irradiation as a function
of the radiation dose for 5- and 10-kov ions. The difference between the
effect of 0 and N2 ions is obvious. Vjaereaa N2 ions do not change the
carrier concentration considerably and increase the defeat density only
slightly (thus somewhat increasing the ohmic resistance), 0 ions increase
the rectification constant (ioeop by forming a p-n junction in the
"active zone" of the specimens, because the penetrating oxygen atoms act
as acceptors), The rectification constant has a maximum at a certain
dose (which is due either to a removal of the region of defeat-carrier
equilibrium from the active zone of the probe, or to an increase of the
lattice defects, or to both). Fig. 4 shows the dependence of direct and
reverse currents and rectification constant on the radiation dose NO
(irradiation by 10-key 0 and N2 ions). The true value lies in the
hatched region. There are 4 figures, 1 table, and 10 references: 5

TITLE: Plasmon spectra in In and InSb
PERIODICAL: Fizika tverdogo tela, V. 4, no. 1, 1962, 86 - 69
TEXT: The characteristic energy loss spectra of electrons passing through
free thin films of In and InSb were measured using a device.and method
described by V. M. Ageyev, L. A. Balabanoval and 14. M. Bredov (FTT, 2, 11,
1960). The films were vacuum-deposited on rock-salt crystals which were
then dissolved. When evaluating such spectra, it should be considered
that the electrons can lose energy by successive excitation of one, two,
or more plasma vibration quanta, or by pair collisions. If there is a
group of valence electrons with sufficiently varying energy, or if the
difference between the plasmon energy corresponding to the electron
vibrations in this group and the energy characteristic of band-to-band
transitions, it will be possible to observe the lines related to the exci-
tation of collective vibrations. If the assumptions made above are correct
the energy losses of electrons due to the excitation of plasma vibrations

where L) = 4ne IT/m, N is the concentration of electrons involved in plasma
vibrations. The lines that follow correspond to the excitation of one,
two, three, and so on plasmons. The plasmon spectrum cannot be observed
in practice when the plasmon energy lies in the spectral ranee correspond-
ing to band-to-band transitions. However, if the lines n ftz(n = 2.3 14.,,,.)
lie in this range, the plasmon spectrum will be observable~ Practical
observations will only reveal transitions between neighboring bands.
Transitions from the valence band to higher bands cannot be observed in
practice under real conditions. It is assumed that chiefly transitions from the
band below the valence band to the latter and to the conduction band can
be observed in practice provided the difference in energy between these
two bands is not too large (10 - 20 ev). Curves recorded on InSb show no
band-to-band transitions, but furnish two distinct lines-corresponding to
single and double excitation of a plasmon with the energy I~Lj= 12~65�0~25ev
with the probability 0.95. The semiquantitative results of the measure-
ments discussed here might show where investigations of the characteristuic
energy losses of electrons can be of interest for solid-state Physics.

TITLE: Variation of the surface properties of p-type silicon under
bombardment with lithium ions
1ERIODICAL: Fizika tverdogo tela, v. 4, no. 2, 1962, 562 - 564
TEXT: Continuing an earlier paper (Dredov et al. F?T, .1, 267, lo,61) an
attempt was made to produce donor centers in p-type Si by bombarding it
with Li ions. Li impurities in Si have a level which id 0.033 ev below
the bottom of conduction band. The irradiation energies and doses were
determined, at which the concentration of the penetrated Li ions would be
higher than that of the displacement defects due to the irradiation. At
a certain depth inversion of the sign of conductivity has then to be
expected. The experiments were carried out with an apparatus described
earlier (Bredov et al. DAN SSSR, 99, 69, 1954); the ion source was
described in Ref. 8 (Bredov, ZhTF, 20, 476, 1950); the ion energy was
5 and 10 kev. The single-crystal samples had a resistivity of 14 4nd 30
ohm-cm and concentrations of 2.1015 cm-3 and 7.10 14 CM-3, respectively.

S/181/62/004/002/048/051
Variation of the surface ... B102/B138
The variations -in direct and reverse currents and rectification factor
were measured in dependence on the doses. Prom the graphs it can be seen
that at doses of the order of 1o14 - 1o15 cm-2 the reverse currents shoD
a sharp rise, and at 10 15 - 10 16 cm-2the rectification factors become
broken* It may be assumed that at these doses a new p-n junction is
formed which is opposite to that which existed before irradiation. The
deDth was calculated, at which the concentration of penetrated ions was
comparable with that of the carriers; 1o-4 cm was obtained for a specimen
with 2.10 15 carriers/cm3bombarded with 10-1rev ions with a dose of 10 16
It is assumed that the depth of penetration of Li ions is greater than
that of X ions. The formation of displacement defects is accOMDanied by
their partial annihilation. These results mean that an n-layer may be
formed in the region of the active zone of the probe. This barrier layer
is responsible for the valve-type photoeffect observed. There are 2

.:showers, therefore, is directly related to the questi6n of the nature of
meteors. At this point it should be noted that the problem under discussion.
does not involve meteors of noncometary origin reaching the earth, the
number of which does not change during periods of meteor showers.
The problem is approached on the assumption that comets are macr6;-,
scopic bodies consisting of antimatter. and coming to us from other solar
systems of our galaxy which may consist entirely of antimatter. From,~
'this, a-plausible theory can be derived to explain the extrasolar-system
origin of comets. A comet's capture by the sun could, according, to calf,
culations, result from a small change in the comet' s total ehergyj ade-
quate to transfer it from a hyperbolic to an elliptical class, due to the
annihilation of protons in th 0
e solar wind n the comet' s surface.

the most satisfa:ctory for detecting the investigated phenomenon are hard
gamma rays (with an energy exceeding 70 Mev), which can'be. recorded-
at a great distance from the point of annihilation.-. Due to the radiation

gamma radiation flux at sufficiently high altitudes permit several maxi-
mum values to be derived for the quantity of antimatter which may enter
the earth' s atmosphere. The intensity of gamma radiation at an altitude

maximum antinucleon-flux- intensity value, and considering the earth I s
".orbital velocity to be .'1- 3 x, 106 cm/sec, the concentration of antinucleons
in space is estimated at about 10-7 CM-3.
Measurements of average. ga~dm a-radiation intensity at altitudes of
~25- 30 km during periods of, arying meteor activity have shown that
v
variation in the intensity of gamma radiation during a period of maximum
meteor shower activity exceeds by not more than 5016 the radiation in-
tensity in the.absence of a shower. This finding permits maximum values
for the mass of antimeteors to be estimated. The number of meteors
failing on a given area of earth per unit of time during the heaviest showers
is about 10-16-10-15 1CM2 - sec7l. Taking, as earlier, the maximum gam-

with its variation not exceeding this value during a period of
-shower activity, a maxi
meteor mum value for the mass of an antimeteor
was found to be about 10-1 - 10-10 g. If such'meteors are antiparticles,
their mass of 10-9 g would release a total energy equivalent to. that of a
conventional meteor with a mass of 10-1 g. The task of registering the
annihilation radiation from,an i vidual meteor should be fairly diffic
ndi ult,
considering that annihilation would occur at an altitude of about 100 km.
Along with measurements of average intensity at altitudes of 25-30 km,
~experiments were conducted to detect radiation at altitudes of 13-18 km
iproduced by an individual meteor entering the atmosphere. Gamma rays
and neutrons were registered by scintillation counters and proportional
gaseous-boron counters; meteors were detected by a,radar technique ai
the 4-m wavelength. Ube directivity pattern of the radar station,. the
selection of meteors' radar echoes by distance, and the area in which to
expose radiation detectors were . coordinated in such a way that it was
;,possible to assume'that a given meteor had entered the atmosphere
approximately above, the detector.

A number of control experim&fits were used to reveal any systematic
errors which could possibly have occurred. Despite this, and since the
experiments were conducted using only one method, the possibility remains',
that unaccounted-for systematic errors were made; however, actual
reasons for their appearance could not be found atth~at time. With the
formntion of meteor trails at an altitude of about 100 km, an increase in
the intensity of hard gamma. radiation and neutrons, amounting to
approximately 216 of the background or v I impulse per meteor, was
!noted at altitudes of 13-18 km.
Among the possible physical origins of the observed effect, besides
the explanation related to the investigated hypothesis, may be suggested
the presence of background modulation of cosmic radiation during the entry
of a conventional meteor into the earth' s atmosphere. Theoretically,
such modulation can take place either because of a change in the derisity
of the upper atmospheric layer or because of the influence of the magnetic
pole on primary cosmic radiation arising during the formation of a
meteor trail.

ABSTRACT. A mass spectrometerIis described which uses as the analyzing medium the
uniform electrostatic field between plane condenser plates. A shaped
beam of charged particles injected at 45* to the field direction will
,describe a parabolic path. as shown in Fig. 1, such that. the dipt~ar~ce V"
of pairticle"
is a energy. Refocused with a magnetic field-'-
applied to the emerging beam as shown, the beam is collected at element
K; energy spectra are then determined from apparatus geometry. Fig. 2
