Reity A. Quasiclassical approximation for the relativistic one- and two-centre quantum mechanical problems.

Object of studies: relativistic one- and two-centre quantum mechanical systems. Goal of studies: elaboration of new versions and development already of known ones of a quasiclassical approximation (WKB method) for the Dirac equation in strong external fields and their application to study features in energy spectra of three relativistic quantum-mechanical problems. Method of studies: quasiclassical approximation. Scientific novelty of studies. Influences of various effects - Coulomb, barrier, exchange, spatial dimensionality and spin-orbital interaction - on spectral characteristics of the relativistic one- and two-centre quantum mechanical problems are first investigated. Degree of implementation: is being planned. Area (branch) of implementation: atomic physics, plasma physics.
