摘要: Many-body perturbation theory has been applied to compute expectation values of the one- and two-electron interactions which yield relativistic corrections (Abragam-Van Vleck terms) atomic gJ factors. A term due motion nucleus is also considered. The present calculations are based on analytic expansions single-particle states, a main purpose work investigate capability this method for computations complex properties. examples considered ground states alkali atoms up rubidium, first-row atoms, chlorine. complete third order some fourth-order diagrams included. For energy lowerings ranging from 82-92% experimental correlation energies were obtained, showing that considerable amount computed factors compared with high-precision reasonable agreements troublesome cases nitrogen fluorine 2P1/2 state among achievements. Correlation effects in several found be importance
