Relativistic Hartree-Fock oscillator strengths for the lowest s→ p and p→ d transitions in the first few members of the Ag(I) and Au(I) isoelectronic sequences, with allowance for cope polarization

Abstract

Relativistic, single-configuration Hartree-Fock oscillator strengths for the lowest ns 2 S 1 2 → np 2 P 1 2 3 2 and np 2 P 1 2 3 2 → nd 2 D 3 2 5 2 transitions in the first few members of the silver ( n = 5) and gold ( n = 6) isoelectronic sequences have been studied, both with and without allowance for core polarization. Core polarization is included by introducing a polarization potential in the one-electron Hamiltonian and by employing the corresponding correction for the dipole-moment operator in the transition matrix element. The results obtained are compared with available experimental data and the influence of core-polarization effects on oscillator strengths is discussed.
