Some new simplifications for general form of the orbit-orbit interaction operator

Atomic Physics 2007-05-23 v1

Abstract

The general tensorial form of the orbit-orbit interaction operator in the formalism of second quantization is presented. Such an expression is needed to calculate both diagonal and off-diagonal matrix elements with respect to configurations, in a uniform way. Some special cases are shown for which the orbit-orbit interaction operator reduces to simple form. The importance of different contributions to the Breit-Pauli hamiltonian is investigated in ground states and ionization potentials for Li isoelectronic sequency in the systematic way.
