TITLE.- Determination of the Parameters of the Distribution
of the Dimensions of Particles
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy, Fizika, 196o,
No.4, pp.60-65
TEXT; The scattering properties of a cloudy medium can be used as
a source of information about the distribution of the dimensions
of the particles composing it. A similar problem was investigated
by K.S.Shifrin (Ref,l) and leads to the inversion of a special form
of the Fourier integral. The particle distribution curve is
obtained by numerical integration with respect to the angles of
scattering of the experimental distribution curve for the intensity
of the light, In the present note an attempt is made to modify
the problem and, using experimentally measured intensities of
light scattered through three angles, establish the parameters of
the distribution function. The use of a parametric representation
of the particle distribution function simplifies the problem
considerably. The distribution function for the particle
dimension is taken in the form
r-In(r) AO'e-cr dr (2)

where c (greater than zero) @L (an integer greater than or equal
to zero) are parameters of the distribtition and A is a normalizing
constant. If the medium consists of suspended reflecting
particles, the intensity of scattered light depends only on the
character of the distribution of the particles according to their
dimensions. The assumption that multiple scattering has
negligible influence leads to Eq,(5) for the intensity of light
scattered through a small angle P. This type of integral has
been calculated in explicit form by Shifrin for ji = -2(1)2, and
leads to the expression for the intensity of the form
111 (a. c) = a- (il + 3) (Pli + 2(k) (6)
where a = 21Tp / X, X is the wavelength, and k z: 1/(@jj+c2/4c,2)

TITLE-. On the Conservation of MesonieCharges
PERIODICALn Izvestiya vysshikh uchebnykh zavedeniy, Fizika,
1960, No.1k, pp-135-138
TEXT- The Dirac formalism has two disadvantages, namely, the
nonconservation of the mesonic charges of nucleons and the fact that
it cannot be used to formulate a relation with scalar, pseudoscalar
and pseudo-vector meson fields, i.e.. fields which preserve their
properties on time reversal, It is argued in the present paper
that these difficulties can be avoided if one uses the generalized
Dirac equation
h 4X + hc grad -X + Mc2 0
i -3 ?@ t i 1 3
(6)
where -/ is an 8-component nucleon wave function. The formalism
based on this equation predicts many of the properties of the
particles which can be described by it. It is possible that these
particles are in fact nucleons, There are 9 referencesz 3 Soviet-,

TEXT: The purpose of the present paper is the investigation of the
recombination reactions of fluoroalkyl and peroxide radicals under ex-1%_
clusion of oxygen diffusion. The dependence of the radical recombina-
tion on the ratio of the amorphous and crystalline phase was studied
on Teflon with different degree of crystallinity. Teflon samples in the
form of films or chips were irradiated by a yCo 60 radiation source
at -60 Mrad. The free radical concentration is in this case
S/1
-10 18 1./cM3. Polymerization took place on the oil bath, the electron
paramagnetic resonance was studied at 100C to determine the free radicals.

The kinetics of the recombination of the radicals A and AO 2 was
determined at different temperatures and degrees of crystallinity
(74 and 46 V.) (Fig. 1). The relative concentration I was referred to
the.initial concentration - 1: 1 (x =@RO 214kO210+"A - LRj/[Rjo. The
reciprocal concentration as a function of time (Fig. 1) approaches
linearity asymptotically corresponding to the bimolecular recombination
reaction. In polymers with crystalline and amorphous phases (polyethylene,
polypropylene, Teflon) recombination proceeds according to the bimolecular
law with different rates in the amorphous and crystalline phase. Assuming

coordinates reciprocal concentration-time (Pi6. 1.--, curve 1), which
corresponds to the square recombination in the amorphous zone, as well
as a section correspinding to the square recombination in the crystalline
zone in the case of higher t-values. According to (2) the straight
line corresponding to the recombination in the crystalline phase cuts
off the section 1/a on the y-axis. The degree of crystallinity may
thus be determined from the recombination kinetics. Table 1 gives the
degrees of crystallinity calculated from the recombination kinetics io2
and and thect-values calculated from the specific weight (according
to d 2.00 + 0.3la(g/CM31). Their agreement confirms the model
suggested and the equality of the initial combination in both phases.
The different stability of the radicals in amorphous and crystalline
phase is confirmed by their decrease in concentration by 25-50 ;-; during

of the concentration of repeated heating. According to (2), the rate
constants of the recombination reactions at different temperatures and
degrees of crystallinity can be determined from the linear anamorphisms
of the kinetic curves of the type of Figs. 1, a and 5-. The recombination
of fluoroalkyl radicals takes place in a measurable rate only at'
temperatures whidh are by 50-700C higher than in the case of peroxide
radicals. The following is written: peroxide radicals:

The activation energy of peroxide radical recombination is 26+3 kcal/mole
in the crystail--tio 11-3 Ill the amorph-3-1:; 7alups
of 20 - 40 knal/mol.e are obtained for primary alkyl radicals in various
hydrocarbon polymers, The re3ombination of long-life radicals of solid
polymers is not determined by their structure but by the poperties of
the mediums movement of the segments of polymer chains. In the amorphous
phase with high chain mobility the rezombination rate is determined by
rotation of small chain parts. In the crystalline phase with firmly bound
chains it is determined by the rotation of long chain parts. In the re-
combination rate of fluorcalkyl radicals the high values of the pre-expo-
nential factors are remarkable, which have al&o been observed in other
polymers (Tabl,e 2). The aotivation energy and the pre-exponential factor
highly differ for various Teflon samples, which was also observable in
many reactions of the solid phase and of the electric conductivity. The

TITLE: The possibility of using the method of electron paramagnetic
resonance to record the active centers in the oxidation of
hydrocarbons in the liquid phase
PERIODICAL: Akademiya nauk SSSR. Doklady, v. 139, no. 6, 1961, 1409-1412
TEXT: The authors studied the applicability of electron paramagnetic
resonance (epr): a) for determining free radicals; b) for measuring the
steady concentration of these radicals in the oxidation of hydrocarbons.
A continuation of these studies will probably contribute to the knowledge
of the kinetics of processes of other types. From the measured values it
is possible to determine directly the rate constants of the elementary
reactions that constitute parts of the entire process. Since the
concentration of the radicals is low, their determination under steady
conditions is difficult. For this reason the active radicals could not be
identified during the oxidation of hydrocarbons in the liquid phase. 2
types of active centers take part in the oxidation of hydrocarbons:

hydrocarbon radicals k and peroxide radicals R6 2' At a given initiation
rate the steady concentration is known for several substances. It is
approximately equal for the following substances: cyclohexene, methyl
cyclohexene, 1-octene, dihydromyrcene, ethyl linoleate, digeranyl,
tetralin, ethyl benzene2 cumene, n-decanal, and benzaldehyde. Under

concentration of the R6 21 at a given initiation rate, is the higher the
lower the rate constant of R6 2 recombination. An increase of the constant
to the threefold increases the steady concentration only to the 1-7-fold.
In aromatic hydrocarbons, tetralin and ethyl benzene, in which the
peroxide group is located at a secondary hydrocarbon atom, the recombination
constant is by 1-2 orders of magnitude higher. Among the substances
mentioned the cumyl peroxide radicals recombine with the smallest constant.
In order to prove the existence of the peroxide radicals their concentration
must amount to at least 1-10 15 to 5-10 15 radicals/CM3. The authors studied

cumerie since they expected the highest concentration in this substance.
They used an epr-spectrometer HX@-2 (IKhF-2) with high-frequenoy
modalation of the magnetic field (A. G. semenov, N. N. Bubnov, PTE,
92 (1959)). During the oxidationg oxygen was continuously bubbled through
tha hydrocarbon. The following substances were used for the oxidation:
1) a2obicisobutyronitrile, II) dioyolohexyl paroarbonate, III) cobalt
stearate, and IV) cobalt acetate. Differwnt initiators give identical
spectra. The spectrum is a wide, almost symmetrical singlet
+2 oersteds) with a g factor of 2.015 tO.001. According to the
shift oithe g factor and the effective line width, this spectrum is
similar to the epr spectrum of the peroxide radicals in the solid phase.
In control testa in which.isopropyl benzene was replaced by ethyl benzene
no epr spectrum was observed in any of the initiators mentioned. Besides,
epr absorption disappeared when the oxygen supply was stopped and when
nitrogen was blown through for a short period. Ad 1) The authors
calculated the steZ concentrations of the cumyl peroxide radicals at
different initiation rates from the known values w i and k6 of Eq. (1).
These concentrations were also measured between 70 and 900C and a

the concentrations of (R6 2)meas lie between 2-10 and 4.10 radicals/cm
The measured steady concentration of RO2 radicals was close to the
calculated one. In experiments with II) the authors measured concentra-
tions of 4-10 15 to 2-10 16 radicals/CM3. The rate constant of decay of
II) into radicals is unknown. The authors assume that its decay rate is
equa.L to the decay rate into radicals. Thus, they calculate theinitiation
rate and find that the measured concentrations of the RO2 radicals are
1/4 tc 1/2 of the calculated values. Since this rate is unknown in
experiments with III) and IV) the meaf;ured and calculated radical
concentrations could not be intercomrared. There are 2 figures, 1 table,

It was shown in an earlier paper that the spectrum X,
of peroxide radicals (ROD in oriented specimens depends on the
oricntation of the specimen in the magnetic field, To calculate the
line form in the c.p.r. s-pectrum. for or@entcd specimens the authors
assumed that (1) the pcroxidc radical has an axial sytmictry of the
g factor and (2) the symmetry axes' of this factor are distributed
randorily in the plane S at right angles to the orientation direction
of polymer chains. The calculation has been carried out to the end
for the-case of an infinitely narrow individual line, when the ex-
ternal magnetic field is parallel to the orientation axis. It has

isoprene at room temperature, owing to quick radical recombination. At
-1960C, cis-polyisoprene showed a spectrum similar to that of' trans-
compound. The concentration of free radicals at -1960C was highe -r than
at room temperature. The kinetics of disappearance of free radicals is
described by an equation of second degree and corresponds to the
recombination R* + R' --> stable product. As the slope of the straight
lines representing the "reciprocal concentration of free radicals versus
time" depends on the dose, it is concluded that in the case of high
doses the recombination is impeded by steric hindrances in the amorphous
part of the polymer. The following effective constants of radical
disappearance have been calculated:
Dose, r-10-6 10 20 37 47
Kef 9 sec-1.104 6.25 4.33 3-34 2-74
Calculation of the degree of cross linking according to P. L. Flory
(J. Chem. PhYs-, 11, 521 (1943)) showed that at 10 Mrad about
600 isoprene units were between two cross links, that the number of cross
links increased with the dose, and that at 150 Mrad 1.2 isoprene units
were between two cross links. The steady decrease of K with increasing
