Abstract: Examination of the features of the distribution of the potential in
crystals, caorpared with the distribution of the electron density, and also of the
quantitative relationships and dimensionality in the Fourier series of the potential.
A new method is proposed for calculating thq average internal potential of crystals,
based on using the values of fel(0): ~av(b) = ll4-5 E fel(O)/12 - Experimental data
related to the phencmenon of electron refraction (splitting of the reflexes on photo-
graphs of MgO)*are given, for which is determined. The
I av(M,90) z 10 - 17 volts,
electron-diffraction method is applicable to the study of the distribution of the
potential in crystals. From the experimental amplitudes ohkl normalized to the
absolute values, cross sections of the 3 dimensional Fourier series are ~'(Xoo),

Abstract: (
,,/,(xxo), p,(xxx) are constructed, and the variation of the potential Al,
Ag and Cu is computed. It is established that a distribution of potentials at tb_~
maximum is apprcaimately the same for all 3 metals and is independent of the direc-
tion of the cross section, i.e., the maxima are spherically symmetrical, but. the
values of the potentials between the atoms are somewhat different. An examination
is made of the effect of the error introduced by terminating the series on the vari-
ation of the potential and on the accuracy of the results obtained.

"A Method of Deciphering F2 -Seriez".
Tr. In-ta Kristallogr. AN SSSR, No. 9, pp, 287-290p 1954.
Deciphering two-dimensional distributions of interatomic function by
vector convergence ("superimposing and shifting") can be readily accomplished by
using a photographic method. Three identical photographic negatives are
prepared on which the transparent places correspond to maxima of interatomic
functions, and the dark places correspond to back-ground. When the negatives are
superimposed on the corresronding shifts$ only those maxima which coincide with
one another are distinguished, which inturn distinguishes the structure. Only two
negatives are required in the case of centrosymmetrical structure. The application
of the method is illustrated using the structure of K ZPtc:L3(NH3)7as an example.

Abstract The aoplication of U-e Fourier series in the electronographic method of
localizing hydrogen atoms in the crystalline structure of diketopiperazine
is explained. The role of diketopiperazine groupings in the structure of
albumin is cliscussed. The presence of hydroven atoms, which form H-bonds
and atoms forming no 41-bonds in-the albumin structure, was established. The
spaces between H-atoms were found to be close to the standard values of C - H
and 11 - H spaces. The electron density in the hydrogen atom maxu= was cal-
culated. Ten references: 6-UFLR rand 4-U3A (1931-1953). Table; drawing.

ABSTRACT: The specimens to be used for structure analysis by elec-
tron diffraction are aggregates of a very large number of
single small crystals rblocks). Hence, to compute the intens-
ity one needs to consider, first, the law of scattering in a
single block, and second, the structure of a specimen made up
by these blocks.
For specimens used in structure analysis by electron diff-
raction, in most cases such conditions are satisfied when the
kinematic 10-heory is applicable, i.e. the blocks are of a small
size. There are, however, cases when dynamic scattering is
observed. Cases of scattering intermediate between the kine-
matic and the dynamic are also of interest; these so far have
not been explained.
In solving the problem for the general case of the spraimen
Ce-rd 1/3 consisting of blocks having any (various) thickness, in the
first place the integral intensity of reflexion by a single

70-3-V20
Reflexion intensities of electron diffraction patterns

crystal is calculated. Subsequently, the structure of the
specimen is taken into consideration; it is described by
introducing the function of crystal distribution among angles
f(m) , as well as the function of their distribution accord-
ing to their dimensions p(A) . A concrete consideration of
the form f(m) for specimens of different types (mosaic
-monocrystals, textures, poly-crystals) leads to the intro-
duction into the intensity formulae of 1 , a factor analogous
to the Lorentz factor in X-ray analysis. The fom of this
factor L has been previously found by the author. The final
formula includes also the function p(A) . If all the crystals
(blocks) in the specimen are small, the general formula is
reduced to a purely kinematic case, and the squares of struct-
ure factors enter into it. If the size of all the blocks
exceeds the critical one, formulae of the dynamic theory are
obtained, into which the structure factor enters in the first
power. A general case may be also d6scribed, when the distri-
bution function p(A) is such that-the specimen contains
blocks the dimensions of which are both greater and smaller
Card 2/3 than the c7ritical size. The intensity of reflexion from such
specimens can be described in sufficient approximation by a

formula comprising both the first and the second power of the
structure fActor.
For the sake of comparison with experiment, precision data
of Lennander, a Swedish author, have been used. He measured
the intentities of electron scattering from polycrystalline
specimens of aluminium, silver and gold. From the line profiles
characteristic of each specimen the function p(A) has been
obtained, followed by a calculation of the intensities. The
values obtained are in good agreement with the experimental
ones. In particular, an explanation of the deviations from the
kinematic law f for gold and silver is given. The scattering
in aluminium is practically completely kinematic, which fact is
quite natural since alumlni= is the lightest of the elements
investigated.

ABSTRACT: The progress of studies in the field of electron diff-
raction during the last thirty years is reviewed. The devel-
opment of structure analysis by electron diCfraction has been
the most important trend of investigation, promoting the
advance of the theory of electron scattering and of the experi-
mental technique.
In establishing the limit of applicability of the kinematic
theory, it is necessary to consider in addition to the crystal
dimensions and ord.2ma'1 numbers of components forming a given
phase, also the degree of complexity of the sti:ucture and its
symmetry. Various experimental data are considered which refer
to revealing dynamic effects in examining experimental scatter-
ing curves, in measuring the banded structur-, on ratterns
obtained in a divergent beam and in measuring the effects of
dynamic birefringence. The possibility of using the Kikuchi
lines and Kikuchi bands for structure analysis is considered.

ented of the Fourier synthesis as well as of the ad-1rant M,7sis
and peculiar features of the electron-diffraction strue
as compared to the X-ray and the neutron-diffraction nethod.
A description is given of the camera used in electron-
diffraction analysis at the Institute of Crystallography. This
is followed by a brief presentation of the results of the
electron-diffraction studies oarried out on hydrates of chlor-
ides of some metals, ay minerals (seladonite); of the inve-
stigations of the position of hydrogen atoms in some inorganic
and organic structures; of the studies of semi-conducting
alloys of Bi, Cd, Tlj Sb, Se, Te and some other elements,
including investigations of the amorphous structure of some
phases of this kind. In connection with the discussion of the
studies enumerated, many important peculiar -features and possi-
bilities of the electron-diffraction mathod are indicated,
namely: precision of locating light atoms, study of the ionis-
ation state of some atoms, a more precise detej--mination of the
composition of phases by the structure method, etc. There are

ABSTRACT: The fourth congress took place in the summer of last year and
was attended by more than 700 scientists from 21 countries.
The Soviet delegation consisted of N. V. Belov, L. M. Belyayev,
G. B. Bokiy, Ye. G. Bronnikova, B. K. V-qnsh -teyn, G. S.
Zhdanovq V. I. Iveronoval A. I. Kitaygorodskiy, Z. G. Pinsker
and S. I. Shcheti~ln- They had a special number of the
periodical "Crystallography" taken with them, which contained
all reports delivered by the delegation on this congress, as
well as a collection of scientific investigations"The Growth
of Growth of Crystalsli. The work of this congress was carried
out by 18 sections. In the plenary sessions lectures were
Card 1/4 delivered on .topical problems of modern crystallography.

The Congress of Crystallographers Held at Montreal 30-58 -3-12/45
On the last two days special symposia on electronography and
on the physical research methods of crystallography wore hold.
Great importance was attached to consultations held outside
the official sessions on various scientific problems. A large
group of reports dealt with the theory, the method, and the
new results obtained by investigations on the atomic structure
of crystals. In the section "Progress in Structural
Determination", A. I. Kitaygorodskiy among other things, dealt
with the correlation theory among structural factors. Much
attention was paid to electronic computors. Also new types
of apparatus were on show in special exhibitions of this
congress. N. V. Belov reported on new silicate structures.
The authors regretted the fact that, in the field of structural
determination, mainly only such structures were precisely dealt
with as are already known. A report on general problems of
crystal chemistry was delivered by G. Shdanov. The report by
G. B. Bokiy and G. A. Kukina dealt upon the crystal chemistry
of the complex compounds of bivalent platinums. A. I.

about the results obtained by alootronographic investigations
of some carbides and nitrites. Radiographic investigations of
displacements were dealt with by V. I. Iveronova. L. M.
Belyayev delivered a report on the investigation of a
distribution of activators in halide-crystals of alkaline
metals. Ye. G. Bronnikovs gave a survey of the methods of
breeding piezo-electrio crystals in the USSR. On a plenary

(USSR).
ABSTRACT: The latest model of electronograph designed by the
authors at the Institute of Crystallography is described. The
beam runs horizontally and the maximum accelerating voltage is
75K. The plate size is 13 x 18 cm and the specimen-film dis-
tance is 700 mm. The line broadening to instrument inaccuracies
is about 0.05 mm; for X = 0.05 A and line radius r - 50 mm
this corresponds to a spacing error of 0.001 A. The multiplet
structure of the 1111 222 and 422 line of MgO are resolved.
There is a small secondary gun for keeping the specimen dis-
charged. The table size is 150 x 60 cm and the stabilised HT
supplies are housed in a cabinet ?3 x 60 x height 150 cm. A
hairpin filament sending a beam through a 0.1 mm aperture in the
Wehnelt cylinder is used and it can be displaced, while
operating, in two mutually perpendicular dimetions. The
magnetic lens has 20 000 turns of 0.51 mm dia. wire. The
sDecimen chamber is fitted with ~,vindows, a universal specimen
Cardl/2 mount and internal illumination. A central valve divides the

apparatus into two independent vacuum chambers, film box +
camera body and specimen chamber + gun installation. The
apparatus uses a mechanical forevacuum pump (RVN-20) and an
oil diffusion pump (TsVL-100). With the oil pump hot, working
pressure can be reached in 4 min. Safety devices cut off the
HT if the cupboard is opened. The apparatus is in production.

ABSTRACT: A crystal holder attachment for the standard EG horizontal-

is at the Ad of a tube"which can be filled with liouid
N21 protruding into the~specimen space. The channel-
through which the beam passes along the axis of the instru-
ment can be rotated about the cooling tube to cut off the
beam which may heat the specimen very noticeably. The
cooling tube entering the camera is surrounded by a double-
walled screen also entering the camera which can also be
filled with liquid N2 to act as a guard tube. The copper
crystal holder is itself surrounded, except for-entrance and
outlet -apertures, with a copper box connected to the cooled
guard tube. Operation without a guard tube proved

is recommended that a cold trap immediately above the
pump should also be fitted as otherwise any condensible

ABSTRACT. A function projection is a projection derived from the
electron density distribution by multi3lication with an
a�bitrary projecting function f(x,y,z . This projection
can be calculated by combining a conditioned projection
and the Fourier coefficients of the expansion of
f(x,y,z) - All known and proposed new forms of projection
can be regarded as variant functional projections.
The functional projection is:
af(xy) = C~ p (xyz) f (xyz) dz W
It can be decomposed by expanding f(x,y,z) as:

ABSTRACT: The 230 ways of arranging asymmetric objects in space
were discovered independently during the last decade
of the 19th century by Ye.S. Fedorov, A. Schoenflies
and W. Barlow. From 21 to 27 May 1959, the crystallo-
graphers of the USSR carried out an International
Crystallographic Conference which was held at Lenin-
grad and timed for the 40th anniversary of the death
of Soviet crystallographer Ye.S. Fedorov. It has been
organized by the Akademiya nauk SSSR (AS USSR) and the
MSK, i.e. Mezhdunarodnyy Soyuz kristallografov (Inter-
national Union of Crystallographers). The 600 parti-
cipants came from the USSR, USA, France, Great Britain,

(Novyy tip svyazey mezhdu strukturnymi faktorami)
PERIODICAL: Kristallografiya, 1959, Vol 4, Nr 1, pp 3-12 (USSR)
ABSTRACT: Exact equations are deduced, which, under certain
conditions, relate strue'arralfactors belonging to
mutually parallel layers of the reciprocal lattice.
These equalities are valid in the general case of
the absence of a centre of symmetry and in structures
with several kinds of atoms. In the most general case
the equalities pass into inequalities and a quantitative
estimate of this situation is given. The type of
equations discussed are distinctly different from those
of Harker and Kasper, of Zachariasen and of Sayre.

both centro- and non-centro-symmetrical cases. For
further ver 4fication the hkO and hk1 layers of
(CH CONH )2' diketopiperazine, were used. Possible ways
of using -C~Le equations are discussed,, the use of modern
computing techniques being suggested., A possible use
is the experimental measurement of structure factors too
far inside or outside the sphere of reflexion. If there
is overlapping, -.-'-he basic equation becomes an inequality,
The basic equation is compared with other relationships
(SayTel Za-,hariasen) and is shown to be connected with
them. There are 5 figures, 2 tables and 9 references')

TITLE: The Use of Functions Isolating a Structure From Among
the interatomic Vectors for Finding the Phases of the
Structure Amplitudes
PERIODICAL: Kristallografiya, 1959,-Vol 4, Nr 4, pp 505-509 (USSR)
ABSTRACT: On the basis of the superposition method, formulae are
proposed for determining-the phases of the structure
amplitudes. The efficacity of one.of the formulae is
verified on the hOj zone of the known-tructure of
seidozerite.
If there is no overlapping and no parasitic peaks the
functions L(i), NF) and M(7r) give maxima which
approximate to e(P) , the electron-density distribution.
In as much as these functions are equal, their Fourier
coefficients are like each other. So knowing the phases
of one of these isolating functions, they could be
attached to observed values of ~'hkj'~ for a Fourier
synthesis. If there Is no centre the process would
Cardl/4 require more care.

The Use of Functions Isolating a Structure From Among the Interatomic
Vectors for Finding the Phases of the Structure Amplitudes
For a centrosymmetric structure, 2r-01 the vector between
centre-related atoms can be found by blamedov's method
(Ref 19). The origin is chosen to be at a centre of
symmetry and the Patterson function can be written as:
P(i) = I/V F2exp I- 2,d + A
H
The Z-function is:
(7r) =-- 2/V,~(F2 . cos 2r&ii:o)ex.p21YAr-j
which, when compared with:
I/ '~ F exp, 2-i"Iffir
V~- H
gives the Fourier coefficients. and M(P) are
treated similarly. The formula actually used is from

Calculation with the above formula is most laborious and
pairs were selected from the 102 strongest reflexions.
A table of JF~ on transparent material which could be
superimposed on another table was used. The signs of
all 378 reflexions were calculated from the formula given
and all but 36 (9.5%) were correct. Using the heavy atom

table of the atomic X-ray scattering power, prepared for
the same publication bYTh:)mas, L. H., Umeda, K., and
King, K., was made available to the authors of this
article. The statistical electron scattering power
values are compute'd according to the Thomas-Fermi-Dirac
