Abstract

The time‐dependent variational principle is used to calculate the frequency‐dependent dipole polarizabilities of 2__p__ open‐shell atomic systems. A general theory is built up to include frequency‐dependent perturbations using the Roothaan–Hartree–Fock (HFR) formalism. The excitation energies corresponding to the low‐lying excited states of the system are obtained from the poles of the dynamic polarizability values. A fairly accurate knowledge of transition oscillator strengths is also obtained from a knowledge of the polarizability values near the poles. The excitation energies and oscillator strengths are compared with available data.

A relativistic configuration interaction method, which can handle a general class of open-shell multiplets as the reference configurations, has been developed by combining the open-shell matrix Dirac-Fock self-consistent field algorithm implemented by Koc and Ishikawa [Phys. Rev. A 49 ( 1994) 7941 w
