ABSTRACT: After briefly describing the principles underlying Fourier
spectrometry, the authors indicate that Instruments based on the in-
terference of polarized beams produced by double refraction In a
crystal have superior transmission (luminosity) than apparatus of the
Michelson interferometer type. In particularit Is recommended to
photograph the interference pattern obtained when the entire wedge is
illuminated by a parallel beam of the light under study, and then make*
a photometric analysis of the photograph of the interference pattern.
To test the photographic method of recording in Fourier spectrometry,
the autbom constructed a breadboard device which enabled them to

analyze emission of not too complex spectral composition in the vidble!
portion of the spectrum. The emission chosen for study was the lumi-
nescence of Rhodamine S. The interference pattern was recorded with
panchromatic photographic plates and the true emission spectrum, as I
reconstructed from the,measurement data, was found to be quite close
to the measured spectrum. The method Is especially recommended for
high-speed emissive processes and for spectra of low-intensity astro-
nomical objects, since the accumulation of the signal afforded by the
photography is then very useful. Orig. art. has: 2 figures and 3

showed theoretically that the form of the absorption band for ad-
mixtures in dielectrics can be represented under definite assump-
tions in the form of the product of two frequency functions, the
first factor representing the smooth bell-shaped curve and de-
scribing the general contour of the abso~_)tion spectrum and the
second factor representing a rapidly -;jciilating function and de-
scribing the so called structure of the absorption band. B. N.
Grechushnikov (DAN SSSR, 99, 707, 1955) investigated the absorp-
tion spectrum of rubidium at the temperature of liquid nitrogen
(the earlier study of the influence of temperature was by K. Gib-

Abstract :Examination of the polarization of luminescence of single-axis crystals.
Polarization diagram computed for single-axis crystals are cited (Vavilov,
Zhur. ekperim. i teoret. fiziki, 1940, 10, 1363). The numerical calcula-
tions are made for a negative calcite crystal and for a positive calomel
crystal. It Is noted that the experimentally-determined values of the degree
of polarization are higher than those computed by Vavilov, probably owing
to the effect of the anisotropy of the medium.

Abstract To investigate the absorption spectra of various small
crystals of organic dyes (up to 0.03 mm in diameter), a
photoelectric microspectraphotometer was constructed.
The source of monochromatic light is the UM-2 monochroma-
tor, and the receiver is a FEU-19 photomultiplier. The
darkness current of the photomultiplier is compensated
for. The instrument can be used for the investigation
of the absorption spectra of all microcrystals or biolo-
gical objects, and also for the spectraphotometric

ABSTRACT: N,E. Veden6yeva and G.G. Lemmleyn found that the
samples of qaartz which luminesce strongly can be
coloured intensively by the action of X-rays.
The identity of the colour centres and the capture
centres which produce thermoluminescence in melted
quartz was proved by Lautout (Ref.1). There are two
points of view on the nature of capture centres. In
the opinion of Yokota (Ref.2) the capture centres are
due to oxygen defects. Other workers ascribe
colouring on irradiation to the presence of impurities
in quartz which are in atomic-disperse state. The

crystals from several places of origin. These
crystals are: (A) Quartz from Volhynia, which can
be intensely coloured by X-rays. (B) (tiartz from
South Urals, which is moro difficult to colour.
(V) Quartz from Polar Urals, and (G) Quartz from
Aldan - samples of the latter two groups can be only
weakly coloured by X-rays. (D) Q~iartz from Elba,
which cannot be coloured by the action of X-rays.
All samples were heated to 4000C and then irradiated
with 180 kV X-rays. Stimulation was produced by
uniform increase of temperature (2 degfinin). Fig,,l
shows the thermoluminescence curves for X-irradiated
cluartz A (curve 1 1 hour's irradiation, curve 2 -
2 hours I, curve 3 6 hours I ) .On all the curves of
Fig.1 clear maxima appear at 175 and 2900C. Fig.2
shows similar curves for samples of quartz A. and
quartz B, irradiated with X-rays for 3 hours.
Card 2/4 The maximum at 1?50C is much stronger in quartz B.

quartz V has an inflection around 1750C, and a wide
maximum at about 2800C. Quartz G has several maxima.
Samples cut from two portions of the same crystal G,
separated by a crack, have quite different thermo-
luminescence curves (Fig.4). Heating of
uncoloured quartz D did not produce any emission.
In the opinion of the present authors the differences
between thermoluminescence curves of quartz from
various places of origin support the impurity hypothesis
on the nature of capture centres. Quartz possesses
structural channels (pores) along the C-axis: when
ions of Li+ and Na+ are introduced into these channels
by electrodiffusion, quartz does not lose its ability
to be coloured on X-irradiation. Fig-5, curve 1
gives thermolumineseence of quartz A befoie intro-
duction of foreign ions; curve 2 represents the same
quartz with Li+ ions and curve the same quartz

for 6 hours. Introduction of Li+ ions strengthens
the l?50C maximum, while introduction of Na+ destroys
the 1750C maximum and depresses the 2900C maximum.
It follows that the depth of the capture centres
producing thermoluminescence is affected by ions
such as Li+ and Na+. There_are 5 figuies and 6
references, of which 1 is Russian, 4 English and
1 French.

ABSTRACT: The temperature do-lumineacence of natural quartz samples from

samples taken from different sites differ both in intensity of
luminescence and in the number and temperature of peaks, This
difference indicates the differont nature of admixture ions

TITLE-. The optical orientation of crystalline grains
PERIODICAL~ Kristallografiya, v.7, no.1, 1961~, 137
TEXT-. Description of a method of orientating crystalline grains
with dimensions up to about 0.5 mm, based on the classical method
of Fedorov, The crystals are orientated by observing the
position at which extinction occurs when they are placed between
Lrossed polarisers, Details of the apparatus are shown in a
photograph. The crystal is stuck to an auxiliary needle and
mounted so that it is at the centre of a hollow glass sphere and
on the axis of rotation of the ring on the Fedorov table,
After orientation, which is facilitated by filling the sphere
with liquid, the required direction is along the optic axis of the
polarizing microscope. A second needle is then set up along
this optical axis and the crystal is carefully transferred to it,
the desired direction of the crystal now being along the axis of
the second needle, The crystals are fixed by the use of the vapour
from glue dissolved in various solutions (e.g. silicate glue

operates on the principle of scanning using high-sensitivity infrared-radiation
receivers. To obtain quantitative dat2, the electrical signal generated in the
infrared receiver is amplified and recorded by a measuring device. The electrical
signal can also be converted into visible light. When using a microscope with this
method it is possible to study various structural flaws. There have been designed
and built instruments that operate using this method: the infrared polariscopo
~PIK-l and infrared polarization scanning microscope to investigate structural
flaws in silicon and germanium crystals.

IABSTRACT t TMW is an expansion of the,,device.and application discussed in a pro--
vious article ~y the saw authorge (Irri4allografTya, 8. 39 1%3). The expansions
finolude substitution of Ia quartz wed .ge in the optical system in order to make use
iof the Fourier ta,"sformation and the addition of extra circuits and instrwoents to
1permit the desired measurements of -near-infrared radiation. The optical arrange-
ment and consta-action of the quartz wed& are shown in Figs. -I and 2. The schemat-
7
.1io arrangements of circuits in'the setup are shown in Figst 3 and 4. The authors
iused the apparatus to study luminescence spectra of several crystals In the visible~
!and near-infrared regions of the spectrum. The results vere not reported in this
'article but were reported previously in a short presentation at the All-Union Con-
fere on Speptroscopy in*159,

T:;XT: Calculations are made showing the increase in -
reflection coefficient with Increase of refractive index n at
the Brewster angle, i.e. from - 20,~ at n a 2 to -0% at n
An estimate is also made of the dependence of the angular aperture
of the incident beam on n when the degree of polarization in not
less than 99%. it in shown that with increase in n the angular
aperture of the incident beam decreases smoothly. For the
transmission of a polarizer to be not less than )0%, with the
angular aperture' of the incident beam -6 - 7% then 4 -
