ABSTRACT: Changes in fatigue strength were determined as a function of residual
stress in 30XhGSA steel heat treated to a % hardness of 36-38. Variations in surftv.,~e
residual stress wire introduced by different strengthening methods: 1) knurl rolling,
2) centrifugal ball method, 3) dry shot blasting, and 4) shot blasting in a stream of
vapor. Residual stress is given as a function of distance from the surface for each
method. ror each method of residual stress application, fatigue curves were obtained
under identical conditions. ratigue testing was done with a symmetrical loading cycle
at a frequency of 1450 cycles/min. The fatigue strength of the steel increased with
rise in the value of compressive residual stress in the surface layer. The largest
increase occurred in samples which were strengthened by shot blasting in a stream of

The proton bundle emerging from the synchrocyolotron of the Xnatituts for
Nuclear Problems of the Academy of Science in the USSR passed through a sys-
tem of collimators and impinged upon a target of liquid hydrogen. The
scattered protons were registered by means of a telescope consisting of
scintillation counters. The charged products of the nonelastic (P-P) colli-
sions (positive pious, protons, and deuteron) were separated from the,
elastically scattered protons by means of filters. The energy of the protons
in the bundle amounted to 657 + 2 MeV and the 460- and 560- MoV protons
were conserved by slowing down irith polyethylene absorbers. Measurements
extended up to an angle of 50 in the center of mass system (- 2,20 in the
laboratory system. The differential cross sections of the (p-p) scattering
found here are shown in a table and agree fairly well with the results obtained
at BIRMINGHAM (L.RIDDIFORDt Proo.Roy.Soo., in print). The present results
make it possible, within the energy range investigated, to obtain precise
data concerning older results obtained for the ratio of the total cross
sectiPas of elastic and nonelastic processes on the occasion of (p-p) inter-
action, and also concerning the data on the total cross section of the re-

action p + p -> n + p + The total cross sections of the various processes
occurring on the occasion of(p-p) interaction are shown in a table.
According to the total number of data at present known concerning the scat-
tering of energy-rich protons by protons, the total cross section of elastic
(p-p) scattering within the energy range of from 800 to 660 MeV is constant
within the limits of measuring errors, and it deareases somewhat if energy
riseB to from 600 to 1000 MeV. Therefore the increase of the total cross
section of (p-p) interaction within the range of from 460 to 660 MeV is due
only to meson-produoing processes. The contribution made by nonelastic pro-
cesess towards the total cross section amounts to 13% at 460 MeV, 26% at
560 MeV, and 40% at 660 MeV. From these data and from the total cross sections
of the reactions p + p -), d + x+ and p + p ---'p p + p + no the total cross
section of the reaction p + p -> n + p + x may be eetimated; the corresponding
values are shown in a table. The total cross section of p + p --,4- n + p + %+
increases with a rise of energy from 460 to 660 MeV by about six times its
amount. The value of this cross section agrees well at 660 VeV with the direct
measuring results obtained by V.M.SIDOROVI Zurn. eksp. i teor. fis, 31, 8

TITLE: On the Angular Distribution of the Positive IjVns Generated

ABSTRACT: First the authors mention several earlier works dealing with
the same subject. The present work gives the results of the
examination of 10.000 (7r?)-decay processes of porjitive
myons which came to a stan still in an 11H OM emulsion of
the P type, The emulsions were irradiated in a positive
beam of the synchrocyclotron of the Laboratory for Nuclear
Problems (Laboratoriya yadernykh problem) and during their
exposure they were encased within a steel screen which pro-
tected them against the action of the exterior magnetic field.
The (Yr-p)-decay process&s were observed by. means of an exa-

largoment. The angular distribution resulting immediately on
inspection is shown in a diagram. The asymmetry coefficient
of this angular distribution is b - - 0,048 + 0,020. Then
the authors shortly report on the estimate oFf systematical
errors. The probability of the observation of a (F--
,a)-decay
process decreases within the range of small values of the
angle Q* between the final direction of the positive pion
and the initial direction of the positive myon. The distribu-
tion determined by direct observation was corrected taking
into account the ragistration probability and the experiment-
ally determined distribution of the angles between the ini-
tial direction and the final direction of the positive
pions. The corrected distribution of positive myons through
the projections of the angles is shown in a diagram. The co-
efficient of asymmetry of this angular distribution is
b a + 0,009 � 0,018. Therefore the angular distribution of
that part of positive myons which are generated by the
2'-p-decay of the positive pions which had come to a stand-
still is isotropic. The cause for the asymmetry observed in
some works can at least partly be connected with a systema-
Card 2/3 tical error investigated in this work. There are 2 figures,

ABSTRACT: An emulsion chamber with loo layers of the type NMI-R,
(with a thickness of - 450 g and with an area of 10.10.cm-)
was irradiated by 9 BeV protons of a synchrophasotron. The
emulsion layers were investigated along the tracks of the
primary protons. On a length of 485 m 1308 interactions of
protons with nuclei were found. The processes of scattering
into an angle of less than 5 0 are not included in this number.
178 of these 1308 interactions are interactions of protons
with nucleons in the photoemulsion. The authors found 115
cases which are similar to (P - p)-interactions and 63 cases
Card 1A similar to (p - n)-interactions. The cross section of the

inelastic (p - p)-interaction at 9 BeV amounts to 30 milli-
barn. Within the interval 1 - 9 BeV, the cross section of
the inelastic (p - p)-interaction is practically constant,
and apparently it is constant also in the region of hig
.,her
energies. 11 of the 115 (p - p)-interactions are due to the
elastic (p - p)-scattering on hydrogen in the emulsion. The
differential cross sections of the elastic (p - p)-scattering
cannot be estimated because the experimental data are in-
sufficient. The total cross section of the elastic (p - p)-
scattering at 9 BeV (with respect to the necessary correc-
tures and of the background due to the quasielastic (p - p)-
scattering (,v10 %)) amounts to
elastic
app . (10 � 4) millibarn. This total cross section is
constant (within the limits of experimental errors) in the
interval 6 9 BeV. An estimation of the total cross section
of the (p p)-interaction at an energy of 9 BeV (the sum
of the elastic and oi'41t-he,inelastic cross sections) gives the
Card 2/4 value -40 millibar--. A diagram gives the angular distributions

of the charged particles due to the (p - p)- and(p - n)-intev-
actions are equal within the limits of experimental errors.
Also the angular distributions of the fast charged particles
due to the (p - p)-:and (p - n)-interactions have the same
values. The average free path for the nuclear interaction of
the fast secondary particles due to the (p - p)-interactions
and (p - n)-interactions is equal to (34 � 6) cm and(28 + 7) cm,
respectively. These values are not different from the free
paths for the interaction of protons and pions with energies
of I - 6 BeV and they also aG-ree with the results obtained
by other authors. According to the results of this paper
the average free length of path for the interaction of 9 BeV
protons with the nuclei of a photoemulsion amounts to

ABSTRACT: When a positive pion collides with a nucleon in a compound
nucleus' two+charged jesong may be foried.by t4 following
reactions: n +p-*11 +.T1 +4 N9 n +n-n +n + ,p
The authors investigated reactions (I) and (II).on the inter-
action of fast positive pions with nuclei in the-phot-emulsion.
An emulsion chamber composed of ten layers of the emuision
NIKFI of the kind R (thickness 400 9, diameter 80 mm) was
irradiated in a beam of positive pions with 307 Mev energy
in the synchrocyclotron of the Laboratoriya yadernvkh problem
(Laboratory for Nuclear Problems) of the Obl'yedlnennyy institut

of primary mesons. 13 (+ 4 probable) cases itith two secondt-ry
mesons were recorded in 300 stare which had been found in the
emulsion layers. In about 40% of the cases recorded only the
track of a secondary particle could be found. When positive
280-iev pions collide with nuclei of the photoemulsion,
these pions in the nucleus are absorbed as often as negativG
pions. Disintegrations totalled 92 with slowed-down negative
pions, and 106 with positive ones. Further investigation dis-
closed that 39 of these 198 diaintegratiQns contained two
secondary charged mesons. A diagram illustrates the energy
distribution of mesons for the cases in which two secondary
mesons were emitted- 7 of 112 investigated mesons possesaad
an energy of more than 60 Mev. The spectrum attained its maxi-
mum within the range 30-40 Mev. The major part of secondary
mesons have an energy of less than 60 Mevy and the mean
energy of the latter amounts to 30 Mov. The second diagram
shows the spectrum of stopped negative pions. It resembles
that mentioned above, yet it is distinctly shifted toward lower
Card 2/4 energies. The mean energy of negative pions amounts to 16 Mev.

Formation of Mesons by n -Mesons With 280 Mev.Energy on Nuclei in a Photo-

The difference in the mean energies of positive and negative
pions (r- 14 Mev) is due to the effect of the Coulomb field
of the nucleus. The angular distribution of pions within
the center-of-maze system is not 0isotropic, and attains a
wide maximum at angles of - 180 . A table shows theangular
distribution of mesons for oases with two mesons. A.diBtinct
correlation in the direction of emission of the two secondary
mesons is noticed here. The cross sections of meson, formation
during the collision of positive pions with nuclei.in the
photoemulsion. were determined by comparing the number of
formation processes with the number of stars produced by
mesons within the same emulsion volume. The medium range of
positive pions for star formation in the emulsion amounts
to (32-4 :4~2-3) cm. The cross sections of the formation of
charged mesons i!~ the processes %_ + nucleus -)- n- and

TEXT: The first results obtained from the investigation under review
were submitted by B, M. Pontekorvo in July, 1959? at the Conference for
the' Physics of High-energy Particles held in Kiyev. The authors of the
present paper wanted to-study the conditions and the energy characteristic
of secondary particles in the reaction n- + p .. o- x- + n+ + n at an energy
of 290 Mev of the primary %--mesons. The angular and momentum distribution
obtained are oompared-with the statistical theory by Fermi and the iso-
baric model by Lindenbaum and Sternheimer. The meson production was
conducted in pelliole stacke, which were exposed to a n--mesoa beam from
the synohrocyclotron of the Laboratoriya yadernykh problem Ob"yedinennogo

mere recorded in the photoemulsion, and in the further analysis only such
cases were selected as exhibited only two mesons among the secondary
charged particles. 135 interactions satisfied these conditions and in
them, the authors seajured the energy of the secondary mesons and the
angle of their emission. An estimation of the reaction oross section, in
which reference was made to a paper by K. S. Bogomolov and M. F. Rodicheva,
yielded a value of (o.61 + 0.13) inillibarns. Fig. 1 is a graph depicting

TEXT: The authors recorded 243 inelastic interactions, viz., 140 PP

on the proton synchrotron of the Laboratoriya vysokikh energiy Ob"-
yedinennogo instituta yadernykh issledovaniy (High-energy Laboratory of

the energy- and angular distributions of the secondary particles, mea-
surements of the multiple Coulomb scattering and ionization were carried
out; the results obtained are briefly discussed. The angular distribu-
tions of the charged pione and protons in the rear semi-space (C.M.S.)

distributions are anisotropic as is the case also with 6.2-Bev. This is
in contradiction to the assumptions of the statistical theory on the
isotropy of the angular distribution of secondary particles in the
c.mos. The mean proton and pion numbers (n p and n 1E ) occurring per in-
elastic pp-scattering event in the rear semi-space in the c.m.s. is
1.3 zt 0.3 and 1.9 � 0.3, respectively. The corresponding values follow-
ing from the statistical theory are 1.2 and 2.3. The following n-ialues
are obtained for the two kinds of charged pions: n n+ - 1.3 � 0-3 and
n.- - Mi + m6. Fig. 2 shows the momentum distributions of protons
and charged pions from pp interactions. It is shown th 'at the pion spec-
trum with respect to the theoretical distribution is shifted toward
smallerg and the proton spectrum toward greater momenta. The average
momenta in the c.m.s. are calculated to be P* - (1.2+0.1) Bev/c and

of 58%). Fig- 3 shows the angular distributions of the charged secondary
particles, taking the correction for geometry into account. The angular
distributions (pp,interaction) are symmetric in the c.m.s. The angular
distributions of the secondary particles from pn~scattering are asym-

PERIODICAL: Akademiya nauk SSSR. Doklady, v. 148, no. 4, 1963,`
793-795
TEXT: In an emulsion chamber irradiated with 9-Bev protons 760 events of
inelastic (pN) interactions (492(p-p) and 268(p-n)) were recorded and
analyzed. The mean multiplicity for (p-p) reactions was 3.34 t 0.06, for
(p-n) reactions 2.76 i 0.09. The secondary particles were identified in
multiple-scattering and ionization-density measurements. The c.m.s.
angular distribution of the c arged pions was slightly anisotropic and
this was traced to the fast n~ component. In both reactions the angular
distributions of the secondary protons were strongly anicotropic. The
anisotropy decreased with the proton momentum. The results are analyzed
from the standpoint of the charge-symmetry hypothesis. The momentum
spectra of the charged piona are much softer than those of the secondary
protons. The momentum spectra of the pions as well as of the protons

become softer as the number of secondary particles increases. If the
multiplicity increases, the anisotrop'y of the angular distribution should
be reduced, but no such reduction could be observed. The experimental
data obtained on secondary protons are not consistent with the statistical
theory of multiple production. The model of peripheral collision gives a
good description of the experiment. If A 2 particles are'produced the
model of single 6eson exchange is sufficient to explain the interactions.
At higher multiplicities it is, however, not sufficient. 'There are 4
