AB Initio Calculations of Atomic Energy Spectra

  • A. P. Jucys
Conference paper

Abstract

In this review paper the main features of ab initio calculations of atomic energy spectra are described. The attention is concentrated to the methods based on the variation principle. The theory of using non-orthogonal (Hartree-Fock or analytical) radial orbitals is indicated. The improved methods of the atomic spectra theory are characterized. These are: a) method of superposition of configurations, b) extended method of calculation, and c) method of incomplete separation of variables. The facts, which hamper mastering of the theory as well as its further development, are mentioned. The necessity of using as much as possible unique mathematical apparatus and more close collaboration between scientists of this field is stressed.
