Three-dimensional quasiclassical van Horn wave functions

A rigorous mathematical basis is given for the general equation for the three-dimensional quasiclassical wave functions recently proposed by Van Horn.     

The generalized WKB method in the three-dimensional case. III

We consider simple examples of applying the generalized WKB method [1, 2] to the study of bound states of multidimensional quantum-mechanical systems.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 128–134, March, 1976.     

Second approximation in the generalized WKB method. II

Methods are discussed for calculating the improper integrals in the basic equations found in the first part of this study for the second approximation in the generalized WKB method.The author thanks A. S. Vasilevskii for a valuable discussion of this study.     

Second approximation of the generalized WKBJ method

The generalized WKBJ method is used to study the phase shifts of the radial wave functions of ultrarelativistic electrons scattered by a central field. The scattering phases are derived for ultrarelativistic electrons within terms of second order in inclusively; the relations found for the scattering phases are more general than the familar Rosen-Yennie expressions.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii Fizika, No. 1, pp. 34–41, Jaunary, 1970.

Vapour-Liquid and Liquid-Solid Equilibria in the System Th(NO3)4-UO2(NO3)2-HNO3-H2O

Vapour-liquid and liquid-solid equilibria were studied in the system Th(NO₃)₄-UO₂(NO₃)₂-HNO₃-H₂O. Hexahydrate of thorium nitrate as well as hexa- and trihydrate of uranyl nitrate were supposed to be formed in this system. Empiric equations of solubility isotherms were derived for 25 °C and liquid phase densities were determined. It was established that nitric acid was salted out into the vapour phase by the nitrates present in the system both separately and simultaneously. Empiric equation was derived that describes the relationship between the HNO₃ concentration of condensate and that of all liquid phase components.
