ABSTRACT: The authors report the results of an e.-cperimental, investigation of tunnel J-
systems containing size-quantized bismuth films., since theory predicts that the
current-voltage characteristics of such a system should reveal a mumber of specific
features that yield information on the structure of the carrier energy spectrum. The
measurements were made on Bi (thin film) - dielectric - Bi (thick film)j, Bi (thin Mmi,
- dielectric - Ag., and Bi (thin film) - dielectric - Bi (thin film) system (Fig* 1).
Vacuum rather thant-a-s6lid1dielectric was used for the gap to eliminate parasitic ef-
fects.. The tunnel system was placed in liquid nitrogen during the measurements* fte
bisinuth films were obtained by evaporation on hot mica in vacumo The Inwastigated
sezWles ranged from to 3,3W A in thickness. The volt-ampere characteristics of

TITLE: Optical characteristics and light field parameters of lake water
SOURCE: AN BSSR. Vesti. Seryya fizika-matematychnyckh navuk, no. 2, 1966, 109-114
TOPIC TAGS: optic property, water, light diffusion, light refraction
ABSTRACT: This work examines methods and certain results of defining the optical
parameters of lake water and also studies the light-field in that medium created by
direct and diffuse radiation sources. To measure total light attenuation by water the
authors used a transparency meter which is described in the text. Light attenuation
is given for 13 wavelengths on 5 separate days. Maximum transparency is shifted
towards longer wavelengths in comparison to seawater. To evaluate visibility of
objects under water both the total index of attenuation by the water and the relations
between indexes of actual attenuation and dispersion must be known. A formula is de-
rived and tabular data given which show that change in lake water transparency occurs
in such a way ftat the absorption-to-dispersion ratio remains the same, Wa hing-out
of a collimated beam of light is studied by having an underwater light source send a

beam vertically downward. The receiver is moved vertically and horizontally to m
ure illumination in planes,perpendicular to the light source axis. Background radia-
tion diffused by the water was studied with a light source and a brightness meter .
which turned at a polar angle of 0 + 180* and at an azimuthal angle of from 0 to 75%
Patterns of change of brightness wi7th depth were photoelectrically measured with a
special underwater light source, direct pho~tography of which, with subsequent micro-
photometry, gave the same result. Orig. art. has: 3 formulas, 2 tables, and 4-

TEXTs The decomposition and rehomogenization of solid solutions of
(K,Na)Cl whose compositions are nearly in equimolar proportion,,*,..,I~ were
studied here by three methods; 1) By Laue diffraction patterns."2) BY
microscopic studies with linearly polarized light in which the time
variation of brightness was investigated- 3) By photometric investigations
of the opacifying of crystals of solid solutions. In the individual
sections of the paper, the authors discuss the changes during decomposition/
and rehomogenization of the solid solutions in: Laue diagram, state of
elastic stresseo of the single crystal of equimolar solutions at the be-
ginning of the decomposition, the opacifying of the crystal of equimolar
solutions on decomposition, and the relations between the effects observed
and their interpretation. Results relating to the time variation and the

dependence on temperature of the effects observed lead to the conclusion
that the decomposition of the solutions studied here takes place in two
stages, In the first stage there appears a spontaneous formation of local
heterogeneous regions which are microscopically small. In the second stage,
there occurs a reorj-stallization of the equilibrium phase. The microscop-
ically small regions formed in the first staCe grow at the cost of others
having the same composition. The stresses between these heterogeneous
regions formed in the first stage and their surroundings decrease in the
second stage by the growth of the heterogeneous region. The continuity
and disorientation are destroyed in the heterogeneous region. Heating of
the disintegrated solution above the solubility temperature T. results in
a dissolution of the heterogeneous regions, that is, a rehomogenization
takes place. There are 11 figures, I table, and 26 referencest 5 Soviet,
