RELATIVISTIC OPERATOR PERTURBATION THEORY IN SPECTROSCOPY OF MULTIELECTRON ATOM IN AN ELECTROMAGNETIC FIELD
Journal Title: Фотоэлекторника - Year 2018, Vol 27, Issue
Abstract
We present the theoretical basis of a new relativistic operator perturbation theory (OPT) approach to multielectron atom in an electromagnetic field combined with a relativistic many-body perturbation theory (RMBPT) formalism for a free multielectron atom. As illustration of application of the presented formalism, the results of energy and spectral parameters for a number of atoms are presented. The relativistic OPT method is tested for the multielectron systems such as Fr and Tm. New approach is elaborated for an accurate, consistent treatment of a strong field Stark effect in multielectron atoms.
