Adjustment of the quasirelativistic equations for p electrons

A development of the techniques for solving the quasirelativistic Hartree-Fock equations for quasirelativistic atomic calculations published earlier [ Phys. Rev. A 74 052501 (2006)] is presented. Trial calculations using these techniques revealed that the one-electron characteristics and spin-orbit splitting are less precise in the case of p electrons. To overcome this problem, a different method of averaging the spin-orbit interaction within the quasirelativistic Hartree-Fock equation is proposed for p electrons. The specific account of the contact interaction in the case of p electrons is discussed. The technique for calculating the spin-orbit interaction constant while using the quasirelativistic radial orbitals is presented. Since the pecularities appear on the level of one-electron interactions, only hydrogenlike ions are investigated. Data revealing how the methods under discussion influence the results obtained are presented.
