TEXT: The polarization of internal conversion electrons in transitions
following P decays was predicted by A. I. Alikhanov and V. A. Lyubimov,
and experimentally discovered by Lyubimov and Vishnevskiy. The theory of
this effect was developed by V. B. Berestetskiy, A. P. Rudik, and B. V.
Geshkenbeyn. The results of the present work were communicated to the
International Conference on the Physics of High Energies (KiYev, July 1959~
The authors investigated the polarization of.gonversion electrons :L'or tran-
sitions following the P_ decay of Tm170, Rel , Hg203, and Pa.233. The
apparatus they used is schematically shown in Fig. 1. The arrangement and

ABSTRACT: The investigation of the decay of even-even nonspherical nuclei
and of the energy of excited levels, especially the cbL.-decay of
Pu 238 and Pu 240, is of very great theoretical'importance.
Investigation of the cK-decay of these nuclei and ofthe levels
of doughter nuclei occurring in this decay is carried out either
by the cx-spnctrometry method, by that of r-jl- coincidence, or,
as in the present paper, by the analysis of the conversion
electron spectrum accompanying this decay. Measurements were
carried cut by meant; of a -apectrometer with toroidal magnetic
field and a-e-coincidence circuit, The method has already been

ABSTRACT: This work investiCates the electrons of the internal conversion
which are emitted from U 235-nuclei subsequent to the a-decay of
Pu 239_nuclei. In the introduction a short report is given on
previous papers dealing with the same subject. These internal
conversion electrons were examined by a lar,~e iron-free 0-spectro-
meter with a toroidal magnetic field. The first paragraph re-
ports very shortly on the experimental technique. The authors
investigated the conversion spectrum of the U27~ up to electron
energies of 35o keV, but conversion lines with an energy which
Card 113 considerably stirnounts the background were found only in the

The Investiv,,ation of the Lower Exited Levele of U235 56-34-4-4/6o
on the Basia of the Electrons of tho Internal Converuion
range from 0 - 105 keV. Three different diagrams illustrate the
ranGes of the conversion spectrum for 0 - 35 keV, 35 - 52 keV,
52 - 105 keV. The ener--ies of the electrons and the intensities
of the conversion lines are compiled in a table. First the
authors repoirt on tho levels I and 11 (13,0 and 51,7 keV). These
two levels I and II are to be regarded as the first excited le-
vels of the rotation band with K = 1/2. According to this inter-
pretation the levels 0, 1 and II must possess the spins 1/2,
3/2 and 5/2 as well as the same parity. Almost all conversion lines
which belong to the transitions 11-0, 11 - I and I - 0 clearly
show up in the spectrum. The authors also determined the mul-
tipole properties of these y-transitions. The level 83,8 keV is
the third excited rotation level of thE! band with K = 1/2, On
this occasion the spin must be equal to 7/2 and the parity must
agree with the parity of the remaining levels of the aFLme band.
The authors found only one transition starting from this level,
the transition III - I with the energy 70,8 + 0,2 keV. Remark-
able is also the absence of the transition YII - 0. From the
Card 2/3 level IV (149,7 keV) transitions start, which is discussed in

The Investigation of the LGwer Exited Levels of U 235 56-34-4-4/6o
on the Basia of the Electrons of the Internal Conversion
greater detail. From the level V (172,6 keV) some weak conversion
lines start. This level seems to have the spin 7/2. Finally a
short report is given on level VI with the energy 234 keV. The
authors also looked for the electrons of an isomeric transition,
but without success. The pu240-admixture in the investiGated
samples allowed also the inlreatif-ation gf the conversion electrons
emitted from its daughter-oubstance U23 . The results of this 235
work show without doubt that the levels 0,I#IIqIII and IV of U
belone to the rote.tion band with K w 1/2. The investigation of
the a-spectrum of pu239 speaks for the existence of a whole series
of higher excited levels of U235, but.the electromagnetic transi-
tions between these levels cannot be 'observed. At the end the
authors thank L.N.Kondratlyev, I.I.Agapkin and C.Chornoy for their
assistance in the moasmrementsf and L.L.Sliv for the information
on the internal conversion coefficients on the L-shell. There
are 4 fiCures, 2 tablesland 13 references, 4 of which are Soviet.

TITLE: Basic theory of diametrical rolling and cold rolling
using two and three roller mills
V 41
PERIODICAL: Vestnik mashinostroyeniyaq,,%Ao- 7, 1961, 49 54
TEXT: The authors elaborate the problem of using three roller mms
as oppoved to two roller mills, for the cold rolling of metals.
This method, they claim, can be used for the manufacture of cylin-
drical objects with diameters ranging from 18 to 20 mm, giving a
very low surface impurity product. The aiithors make the following
assumptions: The contact between the cylindrical viork piece and
the rollers takes place along a straight line, or in other words,
the resultant displacement is the sum of the elementary rotations
through an infinitely small angle. The plastic deformation of the
material is shown in Fig. 1. The authors first consider rolling
by using only two rollers, and then Fig. 1 will consist of a num-

ber of triangles representing thevarious zones of plastic delfoirra-
tion due to the Dressure exerted on Lhe work piece. They state
that these zones of plastic deformation must satisfy the kinematic
conditions existing at the boundaries of the plastic deformation
zone. This approach is recommended by the authors since it gives
the upper limit of the pressure at the contact points, as opposed
to the static consideration of loading which viould only give the
lower They consider the equilibrium of the right hand Dor-
tion of Fig. 1 to obtain an expression for the contact, pressure.

shows that the maximum tensile stresses occur at the center of the
work piece..Vlnen using three rollers a cavity of diameter A (Fig.

reduces the possibility of cavity formation in the center of the
work piece, and, if enough tension is developed in the work piece,
failure doc:a not occur. Peeling is a great disadvant , of the Cold
rolling process, and this could be eliminated by using work pieces
with smooth, surfaces. This method was successful when using steel

face area reductLon was 75 ~a'- Cold rolling greatly increases the
strength of metals. The percentage reduction in surface area and

TEX"r: To improve mechanical properties and prevent the formation of slip

where H is the thickness. Experimental investigations demonstrated that (1) the'
correlation of plasticity with hardening %-ras sufficiently accurate under single
and compound loads in tests for uniaxial tension or compression.; (2) the condition
of plasticity permitted determining variations in the mechanical properties o-f a

TITLE: Specific Heat of the Alloys FeM.Al and FeCoAl (Teployemkost'

PERIODICAL: Zhurnal neorgantcho3koy khimii, 1959, Vol 4, Nr 3,
pp 645-650 (USSR)
ABSTRACT: The true specific heat of the alloys FeNiAl and FeCoAl was
investigated according to various methods of treatment of the
alloys. For the production of the alloys electrolytic cobalt,
nickel, Armco iron, and aluminum with a purity of 99.99 1fa
were used. The melting of the alloys was carried out in the
high-frequency furnace in argon atmosphere. The alloys were
investigated as to their true specific heat and coercive force
H
. The curves of specific heat c
of one and the same
0
p
sample were plotted in softened state and after hardening
at 800 and 1,2500 and are shown in figures 1 and 2. The
course of the c p curve of the alloy FeCoAl shows a maximum
at 7000 and of the alloy FeNiAl at 730-7350. The coercive
force of the softened alloys amounts in the case of PeCoAl to
Card 1/3 250oe and in the case of FeNiAl to 75 0e.

8pecific Heat of the Alloys FeNiLl and PeCoAll SOV/78-4-3-23/34
In hardened alloys at 8000 the 11c of FeCoAl -1 oe and of
PeNiAl = 63 oe. The c P course in hardened qarriples (8000) 1-9
characterized by the occurrence of exothermic effects at
low temperatures. The c p course in samples hardened at
1,2500 proceeds in a similar way. The limit of the exothermic
effect is in the case of the alloy FeNiAl between 300-6000
with a cP minimum at 4600 and in the case of FeCoAl -at
400-6400 and a c p minimum at 5600. The nature of the exo-
thermic effect at 300-6400 could not clearly be determined,
it is presumably based upon the orientation of the /~ and
A phase with a variation of the structural tension in the
alloy. Alloys hardened at 1,2500 have also an exothermic
effect at 640'and 6800. The considerable temperature effect
increases the coercive force H.. There is no dependence
between high-temperature transformation and magnetic hardening
of the Pe-Ni-Al alloys. It was found that in the system
Card 2/3 Pe-Co-Al the magnetic hardening process proceeds slogly.

At higher temperatures the cp curve proceeds 'A -shaped,
independent of the thermal treatment of the alloys, with a
maximum in FeCoAl at 7000 and in FeNiAl at 730-7350. This
variation in the c p curve is connected with the occurrence
of the magnetic transformation in the Curie point. There are
4 figures, I table, and 27 references, 19 of which are Soviet.

TEXT: The data obtained by the present study of the system may be used
for the production of Mg-Mn ferrites which are of great importance in
pulse technique. Double salts of the schoenite type (MgSO 4-K2So4 -6H 20),
whare Mg may be replaced by Fe 2+ , Cc 2+ , Mn 2+ p Cu 2+ , Cd 2+ , and K+may be
replaced 'by NH+, are usually isomorphous and form uninterrupted series of
4
mixed crystals. The initial substances weret MgSO 4* 7H2 0, chemically pure
(NH 4)2SO4 and MnSO 4' synthetized from 99-95% electrolytic manganese. The
method of "isothermal decrease of supers aturation" was used for establishing
equilibrium between the liquid and the 3olid phase. It was developed by
V. G. Xhlopin et al. and has been used successfully by G. I. Gorshteyn.

By this method, equilibrium is established after a few hours, which
distinguishee the method from others, e.g., the method of "recrystalliza-
tion". The authors used a thermostat which enabled simultaneous experi-
menting with 24 samples. Fe was titrimetrically determined by KMn04. Mn
was titrated as oxalate with KKn04- Mg was bromatometrically determined
as oxyquinolate. The ternary system MgSO 4' (NH 4)2504- MnSO 4' (NE 4)2S0 4- E'O
was studied (Table 1). Apart from the different solubility of Mg and Mn
salts, the system seems to be ideal over the entire range of concentrations
of both components. The mean value of equilibrium distribution between
Mg salt and Mn salt is 3.50. Based on the thermodynamic theory of activity
(Ref- 3: G. I. Gorshteyn, N. I. Silantlyeva, Zh. obahch. khimii, 23,
1920, (1953)), the following holds for ideal ternary systemsi
Df /Mg) , D w D In the present case, thiscondition is fully
,Fe ~e/Mn) (Mg/Mn)'
satisfied.. Five inner cuts of the quaternary system were studied (Tables
2 and 3)- For evaluating the solubility diagrams, no tetrahedral model
was used, but the curves were treated mathematically in rectangular
coordinates. The solubilities of the individual components were plotted

on the axes x, y, z. The coordinate surfaces x-O-z, x-0-y, y-O-z cor-
respond to the given ternary systems, and the total octant O-x-y-z cor-
responds to the quaternary system. For any content of the solutions,
the following equation must hold for the surface in the intercepts on the
axis of coordinatess x/a + y/b + z/o w 1. a, b, and a are the solubilities
of the individual salts, and x, y, z are the concentrations of the saturated
solutions. Tables 2 and 3, column III, give the values for the sum
x/a + y/b + z/c of the compounds investigated. Since the values are nearly
equal to 1, it is possible to prove that there really exists an uninter-
rupted series of mixed crystals in the quaternary system FeSO 4' (NH4 )2 s04
MnSO 4' (NH 4)2SO4 -MgSO4(NH 4)2SO4 -H20. It seems to be of special im-
portance to establish an interrelation between the compositions of the
liquid and solid phases, which enables quantitative calculations. The
following relation holds for the relative concentration of the component
A in the solid phase and in the mother lye: D . YA / XA
equ(A/B) `yB x.
Systems for which the value for Dequ remains constant are termed ideal

systems. Their distribution curve assumes the form of a hyperbola following
the equationt YA - -1 D-xA . XA and yA denote the concentrations of the
xA(1-D)
component A in the salt fraction of the mother lye and in the solid phase;
D is the coefficient of equilibrium distribution of A as related to B. It
seems possible to apply this coofficient also to quaternary systems. In this
case, it holds: Dequ(A/B+C) = - YA XA . Tables 2 and 3 give experi-
Y(B+C) x(B+C)
mental results. The ratio Mn-salt concentration/total concentration of Mn
and Mg may be seen from column VI. The change of the distribution
coefficient as a function of the composition of the solution is given by;
D f ( Mn ) in the salt fraction of the mother 'lye. By using
(Mg/Fe+Mg) - Fe+Mn
the method of least squares, the following values are obtainedt
D(Fe/mn+mg)'0'633+0.0278x +1-389x 2, and D .963x2

consisting of 25 % Mg salt, 25 % Mn salt, and 50 % Mohr's salt, corresponds
a solid phase of 36-04 % Mg, 14-11 % Mn, and 49-85 ~ Mohr's salt. Any

.ABSTRACT-. The real specific heat of the intermetallic compound CoAl
of stoichiometric composition was investigated by the method of
continuous adiabatic heating. For the production of the alloys
CoAl electrolytically purest cobalt and aluminum (99.99~6) were
used. The real specific heat c p was measured for the same
sample in hardened and annealed state in dependence on tempera-
ture. The c p value in the hardened samples rises slowly and
shows a sudden rise at 7400. The sudden rise of the c p value
depends on the order and disorder in the CoAl structure. By
hardening the samples at 12500 a greater disorder is caused
Card 1/2 than by hardening at 8000C. At temperatures above 8000 all

ABSTRACT: In order to investigate the structural change in magnetic alloys
by the heat capacity method a new adiabatic calorimeter was
constructed. The device is described in detail and the diagram
shown in figures I and 2. The thermo-elements for the calori-
metric system are indicated. By determining the real specific
heat of cobalt and iron within long temperature ranges the
calorimeter was tested. The specific heat c p of cobalt changes

suddenly within the temperature range 447-478' , Iron shows a
maximum of specific heat c p within the temperELture range
745-7750 which corresponds to the transition from a-to P-phanc.

ABSTRACTt The authors investigated the industrial alloys ANKO-1 and
ANKO-2. For ANKO-1 , the authors found the approximate ccm-
position of lEr% 11i, 1VI. Al, 12% Co, Cu (roots Fe), and for
ANKO-2, 2W. Ni, 9~ Al, 15% Co, 4% Cu (resti Fe), The au'~hors
determined the real specific heat c by continuc-uz adiabatic
heating in a calorimeter (Ref 11) , he alloys were heated to
12500 in an argon atmosphere and then hardened in ice water,
Hardening was controlled by measuring the coe-rcivify Hc by tle
ballistic method. The values obtained for c are _pven in the
figures 1,2, those of H. are listed in a tatle. The findinCii
were as follows: 1) tempering of hardened alloy5 a' low tempara-
tures is accompanied by an exothermic effect. 2) This effecil
is probably caused by the ma,-,netic transformation of the
Card 1/2 magnetic P2-phase. On repeatedly heatinE the alloy, the effect

PERIODICAL: Zhurnal neorganicheskoy khimii, v- 7, no. 6, 1962, 1219-1224
TEXT: The direct static method-is best suited for measuring the dissocia-
tion pressu:rc of ferrites between 10- 2 mm Bg and I atm 0 2 corresponding to-"'-
a temperature variation between'1100 and 15000C. The diagram of the
apparatus (Fig, 1) and the heating system (Fig. 2) ard described in
detail. Before the experiment the gas in the system is removed by heat-
ing to 1500()C for 8 hrs until reaching a vacuum of 1o-5 mm Rg. The air-
tightness of the system is checked by disconnecting the pump system and
seeing that the vacuum must not fall below 10-3 mm Bg in one day.
Complete expulsion of the Cases adsorbed to the apecimotin wan attained by
18 hr heating to 8000C. The specimen is heated to 11000C and the

more. Equilibrium dissociation proosure is usually beached within
20-30 min. Then the furnace temperature is raised by 20-3boc, and the
initial temperature is re-established after 5-10 min, while the pressures
are noted. Measurements also are taken each 500C up to 15000C. The test

TEXT: The authors point to the insufficiencies of the ceram,-cally
produced ferrites with respect to optimum electric and magnetic
properties; the study of these properties is connected with great dif-
ficulties. The shortcomings are due to the type of preparation which in all
cases leads only to homogeneous mixtures of the initial substances. The
authors made the following experiments for producing completely
homogeneous ferrites: 1) production of solid isomorphous solutions of
La and Fe sulfate (double salt) as well as Mn-, Fe- and Cu-sulfate by

Isothermal evaporation with constant salt concentrations in the solutions

shown in Fig. 2. The original paper contains detailed theoretical
explanations (Fig. 1),, An isomorphous mixture of the composition

initial sub:3tances. The content of foreign admixtures of the Purified
substances (determined b~ spectrum analysis) was at the order of
magnitude of jo-3 to 10- %(Table), 2) The thermal decomposition of the
isomorphous mixtures was made on air at 800 and 9000C and in the C02- or
N2 current at 8000C, Fig., 2 shows the curves of the thermal decomposition

of the isomo:rphous Mn-Fe sulfates in the air current at 800 and 900 0C
(in the time - weight per cent diagram the weight of the m-'xtures men-
tioned first rapidly decreases, then remains constant) as well as MnSO 4
at 800 C (flat decrease of weight with time), In the case of thermal
decomposition in the air current a completely nonmagnetic oxide mixture
was obtained according to the composition Fe2o 3+-Mn2o 3' A decomposition in
the C02 current led to a strong magnetic mixture of the composition
MnO+Fe2O 3(=MnFe204)., Hence the changes of the valence states of the metal
ions can be controlled and completely homogeneous products can be obtained
by using an isomorphous mixture. There are 3 figure3, 1 table, and 9
