ABSTRACT: Of all the existing geophysical methods of pl,ospecting,
including the seismic method of refracted waves, the most
reliable and accurate results are obtained in investigating a
crystall-':ne foundation by means of the method of refracted waves.
In a number of regions, particularly in the eastcrn part of
the Russian platform, prospecting of the foundation by means of
refracted waves encounters se-Jous diffij--ulties, paxti -cularly
due to the Dresence in the covering medium of th-'-ck iayers of

ABSTRACT: In Part I of this paper (same journal, Nr 3v 1958) an
attempt is described of applying a low frequency modification
of the method of refracted waves for exploring the crystalline
foundation in cases where the foundation is incompletely
screened/and the results are given wh1ch were obtained in
experimental work in the Volga-Ural region. In this paper a
more detailed evaluation is made of the obtained experimental
method for the purpose of detecting characteristic features
of the observed data and for justifying this m6thod of ex-
ploration. Certain dynamic and kinematic features are con-
sidered which characterise the main waves under conditions

incomplete screening. Quantitative evaluation is given of

also the accuracy and the main trends in terfbeting
the.*.inethod. . It is possible with adequate probability to
distinguish structural elements of the foundation of at least
100-200 m. with incidence angles of at least 10-20. The
errors relating to the relief of the foundation are at present
determined to a considerable extent by lack of information on
the layer speeds in the lower regions of the massif and may
reach 20 to 25% of the real fluctuations at the surface of the
foundation. As an example of the comparison of seismic and
geological data, a schematic structural chart is reproduced
in Fig.6, P.579,which shows the foundation as plotted from
seismic data and also information gained from bore holes; on
the Northern part of the territory a satisfactory agreement
was found to exist between the seismic and the geological
data. One of the wells in the South Western part of the
territory sunk after gaining knowledge from seismic data con-
firmed the presence of a rise in the level of the foundation
whereby the difference between the seismic data and the data

borehole. The borehole cartridge unit consists of a body,
an impact head and a casing. The steel body of the impact
head contains the impact mechanism and the winding-up and
release mechanisms. The impact mechanism has a heavy ram
placed in the cylindrical channel of the body pressed against
the slug by a stiff steel spring. The slug is mounted on the
body through a rubber damper. The winding-up of the ram is
performed by the windxng mechanism and compresses the spring.
When the ram is released, it presses the slug against the
rock whilst the casing takes the reaction. The suspension
rod units, made of duralumin, each consist of 3 bars and have
a length of 2 m. The corresponding bars are connected when
further suspension rod units are added. The operating head
controls the operation of the cartridge by pressing the slug
against the borehole wall, winding up and releasing the ram
through the 3 bars in each suspension rod unit, The weigbt

the weight of each rod unit is 3 kg. The depth of suspension
tan be increased to about 50 m. The elastic energy released
at each-,impact is about 10 - 20 times less than the
explosion energy of a single detonator. It is stated that
the energy of the device could be increased ten-fold. rield
tests with the new device are described. The pulse shape,
although complex, has a simple amplitude-frequency spectrum
and does not depend on the depth or point of impact nor on
the type of wave. The directionality has been found to be near
the theoretical for a source of the type of a concentrated
force. The amplitude spectra of the SH wave excited by the
impact are shown in Fig. 5. It is advisable to place the
device at some depth inside the borehole. Comparing the
frequency spectra of explosion and impact-excited vibrations~
it is shown that the difference is small. Some results of

PERIODICAL: Zhurnal Tekhnichaskoy Fiziki, 19589 Vol. 26, Nr 6,
PP- 1151-1158 (USSR)
ABSTRACT- in the present paper the authors investigated the
degeneration of the energy levels of electrons in
crystals, which are connected with the spatial symmetry
and with the symmetry with respect to a modification
of the time signal. it is known that some crystals have
no insulated energy bands. The article mentions all
spatial groups having these properties. The method
employed in this paper for establishing conceptions of
spatial groups differs somewhat from those described
previously (referen3es 1, 2, and 10). In the electron
theory of solids the electron in the crystal is looked
upon as a partiele in the periodic potential field. Its
wave function co, rresponds to the Schr6dinger (Shredinger)
Card 1/3 equation if it is possible to do without spin-orbital

interaction. It can be represented as the superposition
of the wave functions F_ t]

kE~
If there is no spin-orbital connection, a trivial
degenoration always tak-oa plame which depends on the
orientation of the spin. It is different if spin-orbital
connection plays an important part. Trivial degeneration
vanishes (reference 4) and taking account of symmetry with
respect to the modifigation of the time signal in every
case leads to the conol-ision concerning the touching of
bands. Thereforeg the investigation of every spatial
group in the presence of a spln-orbital connection is
superfluous. All results obtained which relate to the
connection between degeneration of energy levels and the
spatial symmetry of the crystal hold not only in the case
of electrons but also phononag spin waves, exitons, and
other quasiparticles. Actually, only the fact is utilized
that the wave function corresponding to any energy level,
Card 2/3 because of symmetry transformation, goes over into a function

Oa the Contact of hhergy Bands in Crystals 57-28-6-3/34
that corresponds to the same energy. It is, however, clear
that every function describing the state of the phonons,
spin waves, or exitons in the crystal, possesses this
property in so far as the transformation of crystal
symmetry leaves all conditions of the respective crystal
symmetry unchanged. The authors thank 1. M. Lifshits for
valuable discussions of the subject. There are 1 table and

of the space group T 6 can pass by a second-order Phase
h
transition. Examples are FeS2, CoSe2, Sn14, ZrG14,
Fb(NO 3)2~ PbP2O?* The theory was given by Landau (Ref 1),,
According to this theory, there is, connected with each
phase transition of the second order, a certain unreduced
representation of the symmetry group of the crystal which
satisfies the determining conditions, Investigation of
the unreduced representations of the group
T6 showed that there are four such representations
h
connected by t-he vector k = 1/2(h, + b + b,,) where

The circums-,5ance that one and the same representation can
be connected with two different phase transitions shows
that there is the possibility of -the existence in the
(p, T) diagram of a line of first-order transitions
beginning a- a point lying on the line of phase tran-
sitions O-P the second order. In the case examined,
the line of first-order transitions separates phase's

TEXT: By means of the group theory, the author investigates the degene-
ration of electron enerjzv levelAkn a crystal, which are related to
their spatial symmetries. Small 'irreducible representations of the crys-
tal groups are givenp which are equal to the possible m.~ltiplicities of
the energy levels in the case of a given quasimomentum k. In Tables 1-13
it is shown in what manner the groups correspond to one and the same
vector ~ in the various crystal classes. The author finally says that
the results obtained concerning degeneration of energy levels hold not
only for an electron, but also for every quasiparticle investigated in LAP
the crystal. The author thanks-G. Ya. Lyubarskiy for valuable discus-
sions. There are 13 tables and 7 references: 2 Soviet- 3 US, and

TITLE: DeGenqiigcy of energy levels in crystals
PERIODICAL: Fizika'Averdogo tela, v. 2, no. 10, 1960, 2557 - 25056
TEXT: The degeneracy of electron encrGy levels in crystals due -.o
symmetry has been st-ldied with the help of the group theory. Forcud de-
generacy is absent i~,those crystals, in which each element of symmetry
of,,:th!~,space grouR G ;an be represented by the product t h, where h denotes..--.,
either a rotation or a mirror rotation, and t a is a translation by the
vector C~. This kind of degeneracy is possible only in crystals whose sp%,;c
groups contain an element g = t ah in such a way that.t a does not, lie in the
space group. This occurs in all crystals whose space group. contains an
i.nverse or non-trivial screw axis or slip plane. In a previous DaDer
(ZhTF, XXVIII, 1151, 1958), the author, jointly with G. Ya. Lyubarskiy,
has dalculated all space grOUDS for which a vector ~ corresponding to the
degenerate energy-levels coula be found. In that paper, th-e authors

The groups C 2v , C2v , D2h , D2h , D2'D2d,D4h, and 0h , in which forced do
generacy occurs, were not mentioned there. Polloving that paper, the
author now calculates all irreducible representations of all space -:roups
and presents the dimensions of the small irreducible representations of thc
groups Gk' which are equal to the possible multiplicities of energy-level
degeneracies with a given value I of. the qua s i -momentum.^ In these repre-
sentations, G indicates the space group of the crystal, G the point group
(class) of the crystal, G the group of the vector ~, which is composed of
k
those elements g - t ah for which hk = k + holds. Here, may be any vec-
tor of the inverse lattice. The correspor...ing set of rotations and mirror
I
rotations h forms the space group G In addition to the lattice-type
k*
tables for the various syngonies the author also presents explicit re'pre-
sentations for ~ iand for the cases of degeneracy. It is show'n that the
point groups C k correspond to the same vector.i in the various(--ystal
groups. In conclusion, the results are summarized as follows: 1 ) Tricl-inic

The method developed in an earlier work by the author (FTT, 1963t 5t 3156), for
studying the transition of crystals from the paramagnetic state into only those
states in which the total magnetic moment 14 of all crystals was other than zero,
