ABS'RACT: A method is proposed for selecting optimum inhomogeneous
meshes when numer-~
ically solv-ing a system of N ordinary differential equations:
Y,=/(X.Y). Y(x0)r=Y'
(y and f are NN-dimensional vectors) in the x C x Cx segment by a
Runge-Kutta methodl
0
of degree s. Mesh optimality denotes that at point R the
prescribed accuracy c is
obtained in the least possible number of steps. An inhomogeneous
mesh (network) is i:
given by means of constantX , termed the parameter of the network,
and the continuous-,--
ly differentiated function ~(x) of the distribution of the network
steps so that at
any node xi (-[x0, x) integration step hi is determined by
Card 1/2

ACC NR, AT6035242
Optimality of the network is achieved by proper selection of
netwo'67'parameterX and
functioa ~(x). The algorithm in question is for the solution of
eq. (1) and embodiesl'
a preliminary computation which, although;it does not give y(R)
with the necessary
accuracy, still makes it possible to compute Xand gx), which
makes it possible to
achieve the required accuracy at point Rx on the second
calculation. The paper gives
a method for solving Eq. (1) when N - 1, and adduces two
examples of Cauchy problems
solved. Orig. art. has: 10 formulas.

TITLE: Isotopic Exchanre in Iron Catalysts
Used in tile Synthesis of Ammonia (IzotopnTy obnen
v molekulyarnom azote na zheleznylzh katalizatorakh sinteza
a-mmialza)
PERIODICAL: Dok-lady Akademii nauk SSSR, 1958, Vol 123,
111- 1,
pp 90 - 92 (USSR)
ABSTRACT: It -,as proved (Refs 1-3) that the addition of K
20
and Al203 to the iron catalysts increases their specific
activity (related to unit surface) with re6lard
to the synthesis of ammonia at high pressure. Once or
twice activated samples have proved to be much more
active than a non-activated iron catalyst. The acti-
vating effect of K 20 was more marked than that of A120 3*
The published views re,~arding the effect of these
additions at atmospheric pressure are rather at
Card 1/4 variance (Refs 4,5). Thrrefore an additional, more

comprehensive investigation of the problem under
review with various contents of activator became
necessary. The method of the experiment was already
previously described in detail (Ref 5). Table 1 gives
the valuesof the activation energy, of the order of
reaction and of the specific catalytic activity K(P't)
at corresponding pressure and temperature for the
samples investigated: It can be concluded from this
that the activated catalysts, as far as their specific
activity is concerned, considerably surpass the Armko
iron (without activator) (in accord with reference 5).
There is quite a definite parallelism in the accelerating
effect of the mentioned additions exerted on the
processes of the ammonia synthesis and of the isotopic
nitro-en exchange. This fact is difficult to under-
stand if it J.s taken for proved (Refs 7-9) that the
limiting stage in the ammonia synthesis is djLe to the
hydrogenation of the adsorbed nitrogen. If it is
assumed that the isotopic exchanCe and the synthesis

the rates of both reactions may be quantitatively
compared with each other. Here, the filling of the
surface,of the catalyst by the adsorbed nitrogen
muot be cosidered (Ref 5). The calculation shows tiiat
the absolute ratr~s of reaction of the amnonia synthesis
and of the isotopic exchange proved to be similar in
samples once activated and in Armko-iron, at equal
covering by adsorbed nitrogen (the data of N.M.Ylorozov
from the laboratory of Professor M.J.Temkin were uti-
lized). Thus, the evidence presented in this paper con-
firmed the mechanism of Temkin-Pyzhev (Ref 10) regarding
the isotopic exchange on iton-ammonia cattilysts. There
are I table and 10 references, 7 of which are Soviet.

ABSTRACT: The longevity of XenopsyZIa fleas after a highly
successful extermination
of their gerbil hosts (species Rhombomys opimus) in 1959-1961 was
studied in the
Sary-Ishik-Otrau sands. XenopsyZla skriabini and Xenopsylla
hirtipes fleas
.represented 96-97% of the original population of fleas in rodent
burrows. it
was found that fleas which had not fed since autumn and fleas
hatched before or
after gerbil extermination, died by the followinj spring. Of the
fleas surviving,
most atill had traces of blood in their stomachs. After
extermination, the number of
fleas per Serbi-1 colony dropped (fall to spring) from 1565 to 61
in sands and from
4244 to 297 in soils overgrown with saxaul plant. Two years after
extermination, the
flea population was reduced more than 100 times, although 20-40% of
colonies were
still inhabited. Orig. art. has: I table. (WA-501

TOPIC TAGS:. flaw detection, ultrasonic flaw detector, acoustic
echo, hermetic seal,
piezoelectric crystal, ultrasonic absorption
A13STRACT: The authors describe two ultrasonic methods for
inspection of hermetic
sealing: the shadow method and the echo method. The shadow method
is based on the
fact that flaws filled with air or some other gas are nearly
opaque to ultrasonic
vaves so that shadows are formed behind them. Calculations show
that interlayers of
air begin to show transparency to ultrasonic energy at a
frequency of 5 Mc only when
t:aey are less than 10 5 mm thick, and show 80% transmission when
the thickness reaches
1,) 8 mm. The shadow method gives reliable results since flaw
clearances are normally
laxge. The dimensions of the shadow are equal to those of the
flaw at a distance of
1-~ss than D3

vUere D is the diameter of the flaw and A is the ultrasonic
wavelength. There is a re_~
auction in the size of the shadow due to diffraction at large
distances, and the dimen-1
si*ps can be found from. the formula
Dr - D-2(L -I) Ig
where L is the distance from the flaw to the reception point, and
a=1.22X/D is the
angle of divergence of the ultrasonic waves. The degree of damping
and dispersion are
considered. The pulse-type UDM-lm ultrasonic flaw detector was
used for checking the
hemetic sealing of joints by the echo methods. If the joint is
airtight, part of the
pulse energy is transmitted to the piezoelectric plate and part is
reflected. The flm
detector screen shows a single incoming signal if the ultrasonic
beam is damped to any
extent in the joint. If damping is not significant,, the signal is
reflected several
tijues from the surfaces of the joint and a damped wave is
observed on the screen. De-
structive tests confirmed the nondestructive data as to size,
shape and location of
flaws. The echo method does not require access to both sides of
the joint and is
presently widely used in industry. Much thinner gas and air
interlayers can be de-
teo.ted 1)), this method and its sensitivity is also greater than
that of the shadow
me",;hod. Flaws can be detected down to 40 =2 under ordinary
conditions, while special
conditions permit detection of flaws as small as 3 mm2. Orig. art.

TITLE: Preparation of d1borane by hydrogenation of

TOPIC TAGS: diborane, chemical synthesis, boron compound,
NY1D066FA)ArrOA
ADOTRACT: Diborane has been prepared by a new method involving
hy&-o-
genation of allcyldichloroboranes at atmospheric or high
pressures.
Identification of the reaction products by IR spectroscopy
Indicated
that the hydrogenation probably proceeds via the B-C bond without
alf-
fecting the B-Cl bond to form dichloroborane: RBC12 + H2--4 HBC12
+ RH.
Diborane is probably formed as a result of the disproportionation
of
HD~12. The results of experiments conducted at atmospheric
pressure
and 250-540C In a flow app6ratus,glven in Table 1 indicated that
the
allcyldichloroboranes are hydrogenated only in the presence of
SKLT-D
or AR-3 carbons. Lower degrees of conversion based on HBC12, as
com
pared with those based on R11, indicated that the diborane formed
u'nd;r-
goes pyrolysis on the-catalyst. Experiments at 300-340C and
hydrogen
pressures of 100-200 atm (Table 2) yielded diborane in the absence

ABSTRACT:
The article
describes the causes of spring breakage of the

above regulator
and gives the results of laboratory re-

search. The top of the
fatigue destruction zone aeemed to

be the origin of cracks.
Pulsations of 2 to 3 mm amplitude

were stated in the levers of
the regulator, from where they

were transmitted to the springs.
Some measures taken to

eliminate these pulsations, lowering tv,em
to 1 mm. Later it

was stated, that the vibrations of the
regulator were in-

fluenced by the operation of the worm gear
between the tur-

bine axle and the regulator shaft. The side-gap
in the worm

gear was about 1.3 mm. It did not influence the
operation

of the worm gear, but it caused periodical pulsations
in

the regulator shaft and in the levers and springs. After

having.carefully adjusted the new worm gear and centered the

shaft of. the regulator with that of the oil pump, the pul-

ped. This resulted from research. The permissible value
of the side-gap in the worm gear must not exceed 0.5 to
0.6 mm. The recommendations of the IIIAIZII for replacing
the 4-mesh worm gear by a 3-mesh one to increase its
strength are not justified$ According to the experience
of the author, a 4-mesh worm gear is sufficiently reliable
if carefully adjusted. There is 1 diagram and 1 photo.

ABSTRACT: The use of the Wilson cloud chamber in investigations
of the interaction between high energy gamma quanta,
though cumbersome, has the advantage that it makes possible
an analysis of practically all the nuclear processes
initiated by the radiation. in the gas. In the present
article the authors describe a few interesting problems
occurring where the Wilson chamber is used in the investi-
gation of photonuclear processes induced by high energy
gamina-radiation (maximum energy 260 MeV) from the synchro-
tron of the Institute of Physics of the Academy of Sciences
of the USSR. The synchrotron generates impulses of Samma
rays at the repetition frequency of 50 secs7' In order
to obtain the best possible working conditions for the
cbamber a special working regime had to be established for
the synchrotron and the working of the chamber synchronised
Card 113 with the emission of the radiation pulse. The procedure

adopted was that given in reference 3. The procedure
involves an application of the chamber to gamma ray studies
with practically no loss in the efficiency of the accelera-
tor. The intensity of the raPated beam of the above
synchrotron is 2 x 10" MeV/cm at 260MeV, and at 10m from
the target. The enerEZr flux per pulse is approximately
7 X 107 ,,eV/cm2. Special measures based on the results
of reference 3 which are necessary to eliminate the electron
and positron background had to be applied. These measures
were :- 1) the beam was injected into the chamber through
a side window covered by an organic film ?G~L thick-, 2) the
beam was collimated by a lead collimator 15cm long placed
at 3.5m from the chamber; 3) a magnet placed behind the
collimator removed positrons and electrons from the y-ray
beam; 4) an evacuated tube was placed between the collimator
and the chamber so as to eliminate electrons and positrons
formed in air. As a result of the above precautions the
number of unwanted electrons and positrons associated
with the tgamm beam was reduced by a factor of 1000.
The following working procedure was adopted. The main
expansion was follovmd by a fast (0-5 sec) compression
Card 2/3 and then by a slow expansion f olloved once more by
a fast

120-2--8/37
ka Application of the Wilson Cloud Chamber to Photonuclear

compression. As a result of these procedures the chamber
was effectively cleared of droplets after each expansion,
the ejectron background was reduced and y-ray beams of up
to 10 MeV per pulse could be employed with the camera
set for the detection of relativistic particles. In the
case of strongly ionising particles the working y-ray
intensity can be increased still further (by a factor of
5 - 10) if one works with a lower chamber sensitivity.
A graph of the synchrotron output as a function of time
(under working conditions), and 3 cloud chamber photographs
are given. There are 6 references, 5 of which are Slavic.

ABSTRACT: A Wilson cloud chamber which operates in a magnetic
field
is described. It can be used to study photonuclear reac-
tions. The workinj~ regime has alroady been .-iven in a pre-
vious paper (Ref.1). In the present paper a description is
given of the various parts of the chamber and of the auxil-
iary apparatus, i.e., the control apparatus, the apparatus
synchronizing the work of the chwabor with that of the syn-
chrotron, and the apparatus used to measure the intensity
of the emitted pulses which are recorded by the Wilson
chamber. An iiupcrtant part of the chamber is an organic
film ?OVL thick ;hich serves as the window through which the
y-rays enter the sensitive voltune. The film is 30 "nan in
diameter and can withstand a pressure of the order of 3-4
Card 1/3atmospher.es. The method of mounting of the film is shown

in Fig.l. An electrostatic field of -40 V/cm is established
be-tAveen the glass lid and the bottom of the chamber. This
field removes ions formed within the volume of the chamber
during irradiation. The pressure in the lower volume of
the chamber is stabilised torJO.01 atm. using a mechanical
pressure stabilizer shown in Fig.2 and develoDed by D. V.
Enellyanov. A detailed description is given of the control-
ling and synchronizing devices. "Ibcact" operations (expan-
sion of the chamber, separation of sinCle pulses, illumina-
tioni etc.) are controlled by the circuit shovm in Fig.4 and
the "rough" operations are controlled by the circuit of FiG.5
The absolute Seam intensity was obtained by meassuring the
activity of a graphite specimen placed in the y-beam. The
chamber was used to study photodisintegration of He at a

plane of the chamber bottom were
chosen and the momenta were

ABSTRACT: This work investigates the reaction He4(y,pn)D and gives
a
compilation of the results of the investigation of ne4 photo-
desintegration. The investigation of this reaction is of inter-
est in connection with the verification of the model suggested
by Yu. K. Khokhlov ' (Reference 3) and J. S. Levinger (Reference
4), of the absorption of photons rich in energy by nuclei. Firal
the authors describe the evaluation of the results. A diagram
illustrates the curve of the cross section of the reaction
He4(y,pn)D in dependence on the energy of the photons. This
reaction has a resonance-like character with a maximum at an
energy of about 50 MeV. The cross section in this maximum is
about 2.1o-28 cm2. In the case of a photon energy of the order
of 75 MeV the cross sections of the reactions (Tan), (1,P)
Card 1/4 and (y,n) are about equal to each other. A table gives
the inte.

gral cross sections of the reaction (y,pn). At energies below
75 MeV the contribution of the reaction (y,pn) to.the integral
cross section of the absorption of photons is les's than -1o%P
while in the energy range above 75 MeV it increases to more
than 30%. 3 further diagrams illustrate,the angular distributior
of the protons, neutrons, and deuterons in the center of mass
system for,the ranges of the photon energy 25,9 Mev (threshold
Yalue) to 75 MeV and from 75 to 170 MeV. The angular distribu-
tions of the protons and neutrons which form in the reaction
(y,pn) resemble very much the angular distributions of the pro-
tons and neutrons which occur in the photodesintegration of a
deuteron. The angular distribution of the deuterons in both
above mentioned intervals of the photon energy is almost iso-
tropic. Then the authors report on the correlation between th6
particles. At the photon energies aboye 75 MeV the neutron and
the proton predominantly were emitted almost into opposite di-
rections. The quas'i-deuteron adsorption of the photons at low
energi%s and also at ener ies above 75 MeV seems to be reapon-
sible for the 5eaction Het(y,pn)D. The reactions He4(y,p)H3
and He4(y,n)He are caused by a direct single-particle absorp-
Card 2/4 tion of the photon, where the electric dipole
absorption plays

the main role. At the energies above 30 MeV the influence of
the electric quadrupole absorption begins. The relative in-
fluence of-the single-particle and of the two-particle absorp-
tion depends on the energy. At energies above 75 Mev the con-
tribution of the two-particle absorption to the integral cross
section of the absorption is at least 3o%. For the integral oros
section of the absorption of photons the value a int' 95 � 7

TEXT: The three photonuclear reactions mentioned in the title
were
studied with a view to obtaining information on the interaction
of photons
in the energy range 30-260 Mev'with nuclei. The experiments were
carried
out with the 260 Mev synchrotron at the Institute mentioned under
association. The maximum enerGy of the synchrotron could be
determined
with an accuracy of �21%c. The targets were prepared from
high-purit-y
materials. The activity of the samples was measured with three
equal
41T assemblies of p counters. During the experiment, the
measuring
apparatus was checked by radium standards. Fig. 1 shows the
dependence
of the yield from the three reactions investi~;ated on the
energies of
the photons. Their differential cross section was calculated
from this.

The results are shown diagrammatically in Figs. 2-4. From the
discussion
of'the results obtained here, the conclusion is drawn that for
photon
energies above 60-80 Mev the interaction of the photons with
the nuclei
takes place without the formation of a compound nucleus. The

dicates that (p pn) is the main reaction for N , though its

to the

yield of (r, pn~3o._) reaction on N exceeds those for 0 and Ne

ABSTRACT: In order to observe the theoretically predicted intense
dipole level of carbon above 30 MeV, an investigation was made of
the
photodisintegration of carbon at energies above 30 MeV. This was
done by investigating the (,y, p) reaction on carbon with a cloud
chamber in a magnetic field, placed in a bremsstrahlung beam
iv'aith-
maximum energy 17Q MeV. A total of 5207 reactions in carbon was
found in 18,000 pictures. The plot of the cross section of (-~, p)
reaction calculated from these data indicates that the maxima

in the cross sei~ion are connected with the excitation of two
differ-
ent levels of C i.~ The position of these levels and their total
in-
tegral cross section are in good agreement with the position of
the
expected irtense,dipole level and with its integral--cross
section,
which amounts to.;15--20% of the dipole sum. The total integral
cross
section of the (y,,*..p) reaction from threshold to 170 MeV is
122 + 5
MeV-mb, and the integral cross section up to,37 MeV is 102 MeV-mb,
or 85% of the total integral cross section. The total integral
cross
section of the reactions (,y, p). (-(, n), and (,y, pn) from
threshold
to 37 MeV accounts for almost the entire cross section given by
the
sum rule without allowance for the exchange forces. Orig. art.
