ABSTRACT: The authors study some problems of heavy-current commutation ai-A erosion
of electrodes made of refractory metals (Mo W) In a vacuum. An analysis is made of the
diffusion products precipitated on various FaN layers. The erosion of Mo, W electrodes
has been determined in a vacuum In a.pulse discharge. A qualitative dependence of the pro-
ducts of erosion on the parameters of the circuit Is detected. A possibility Is established
for the creation of coatings of refractory metals of various density.' Orig.. art. has: 4 figures.

Ions of "medium" energies were employed. These 11medium"
energies are defined as the energies at which no
ionization occurs due to the Coulomb interaction in the
motion of the particles. The upper limit of such
'Imedium" energies is of the order of 5-1U0 keV, depending
on the ionic mass. Only a small number of papers have
appeared so far on luminescence due to ionic excitation

ionoluminescence with cathodoluminescence as the basis
of their measurement. The same place on the screen
was irradiated by an ion beam and an electron beam. One
source of ions and electrons was used, together with a
focussing system anda receiver, which included the screen.

authors found the same to be true for the phosphor
CaS04-bln. Decomposition (ageing) due to Nal K and Cs
ions is irreversible. Decomposition by Li ions is
partly reversible. The process of ageing is due to
:1 structural damage produced by themoving ion in the
crystal. The results obtained in the study of iono-
luminescence may be used to explain certain aspects of
interaction of ions with solids. Althoueh-the path of'
an ion in a crystal is much less than the path of an
electron of the saj-.,io energy, the density of ionization
(or,-more correctly, the density of excitation) due to wl
ion is of the same order as that of' an electron. The
r4echanism of ionization proposed is that on approach of
an ion to an atom~in a crystal, and. on displacement of
such an atom, a strong deformation of the electron clouds
occurs. In such a process the excess of potential
ener6y may be,transferred as the oner,~y of excitation
to the. 01"O'etrons iii such clouds. Depth of the action

layer penetrated by ions. The depth of this layer
was measured by ccuipwing- cathodoluminescence on a -fresh
and an aged phosphor; in the latter case electrons
had to traverse the layer in which luminescence was
destroyed by ions before they (electrons) could excite
the phosphor. Table 2 shows the estimates of depth
of penetration (in R) of Li, Na, K and Cs Ions of
2.4-6.0 keV in willemite. This depth of penetration
by ions is found to increase.with ion energy. Once
again the behaviour of lithium was quite different from
that of the other three ions. A mothod olmilar to
that just described for measurement of the penetration
,depth can be used to find thickness of the iayer removed
(pulverized) by irradiation of a phosphor with iona.

CuSI,CdS-Cu, and sublimate:Dhosphors: KJ-Tlj NaJ-Tl; CdBr 2;
CdJ 21 activated by Mn and Pb were investigated. The excitation
~was performed by positive ions of Li, Na, K, Pb and Cs with
energies from 0.5 to 6 kev.
The basic method of investigation was comparison of ionolumi-
nescence with cathodolumineseence.
Results of this investigation are as followas

sentsiya kristallofoeforov pri vozbuzhdonii ionami)
The luminescence spectra of a "fresh" phosphor and a phosphor
subjected to a prolonged irradiation by an ion beam are the
same. The brightness of luminescence is proportional to the
density of ion current and linearly depends on ion energy.
The light output of ionoluminescence depends on the mass of
ions. For willemits it amounts to 4 % of cathodoluminescence
output at excitation by Li +. and about 0.5 % at excitation by
Cs+. Th'.e quantity is different for.various phosphors.
The deterioration of luminescence (aging) of a phosphor is
determined by' thedensity of irradiation. The speed of aging
is different with various phosphors and.does not depend on the
concentration of activator. Zinc-sulfides are most liable to
aging, and alkali-haloid sublimate-phosphors are the least
liable.
A scheme of the aging process and mechanism of ionization, which
is brought about by a heavy partible in the solid body, is
suggested by thi authors.
The report was followed by a discussion.

ABSTRACTs The authors ihvestigated the yield of positive and negative
photomesons with energies between 0 and 3 Mov at the angles

Work was carried out on the synchrotron of the PIAN with a
llimation of thef-beam

was carried out by means of a lead block with a 3.21 mm2 cleft;
a magnetic field of 7000 oe eliminated the charged

5 , the energy losses amounted to 0o1 Mev for 3 Mev mesons;
the targets were fastoned.to fine caprone fibers (0-0015 mm
thick), which were located outside the beam. Mesons were
recorded by means of NIKFI-K.plates with an emulsion layer
of 4001j, thickness. During irradiation the target and the
plate were in a vacuum chamber which was surrounded by a
lead- and graphite protective shield (of. Fig I).
Evaluation of the plates with respect to pion stars
(negative pions) and -ir - p decays (positive pions-) was
effected with a degree of efficiency of 96 - 98 ~'P. Energy
measurements were carried out with an accuracy of _+ 3
When calculating the meson production cross sections,
charge exchange and inelastic meson nucleon scattering
were not taken into account; for slow mesons these effects
small. Results are shown by figure 2 in form
of a diagram, which shows the pion yield ih dependence of
Z. Curve I corresponds to the meson production on the

figure 2 says exactly the contrary, so that probably
the authors committed an error3. Figure 3 shows the
ratio betwoon tho yielda of pooltivo and negative mesons
as a function of Z. The curve (Z) shows a steep
decline with growing Z, which may be explained as being
due to the interaction between the departing mesons and
the Coulomb field of the nucleus. A comparison between
experimental.results and the theoretical calculations
by A.: M. Baldin and A. I. Lebedev (Ref 8) shows that meson
'production apparently occurs on the surface nucleons of.the
nucleus. The authors finally thank V. 1. Veksler for
supervisingthe vmi; and they also thank A. M. Baldin and A. I.
Lebedev for discussibna.,There are 3 figures and 8

.-TEXT: The yield of charged photome sons in, in general, proportional to
.2/3
A: but the ratio for high-energy pions % denoted by K-IN+, shows
a considerably higher value for some nuclei, thus also for beryllium. Thus,
N-IN+, for'56-Mev mesons produced by photons of E = 256 Mev, Is equal
max
to 3.3�0-3, whereas, according to the,A 2/3 law, it ought to amount to only
1.51. For Blow mesons, the law is, however, cerrect. To explain this
diBerepancy,:the authors measured the ratio ff"'/d+ for pions of medium
energies on beryllium. By means of the 250-Mev photon beam from the
synchrotron of the FIAN, a 3-mm.thick beryllium target was irradiated;
the.mesons leaving the target under an angle of 90 0 to the photon beam

showed.a 6old-brittleness threshold at a higher temperature
than alloys with 0.5% Cr. The minimum plasticity shifts towards
lower temperatures with decreasing-speeds of deformation.
Chromium had no influence on the hydrogen embrittlement at high
rates of deformation; at Iow rates of deformation embrittlement
was more pronounced in the alloy with 5% chromium than in the
alloy contain'ng 0.59, Cr. This -difference was the more
pronouncedthe lower the test speed. The presence of a minimum
on the curves of contraction versus test temperature can be
explained by the occurrenceof additional barriers impeding
movement of dislocations. These additional barriers are dis-
locations made immobile by clouds of hydrogen atoms. Dis-
appearance or -the barriers may be the consequence of diaplacement
of dislocations that.have been stopped earlier, together with
hydrogen clouds surroundinj~ them.
