Abstract
The influence of core polarisation on relativistic oscillator strengths has been studied for the 4s2S12/-4p2P1/2,3/2 and 4p2P1/2,3/2-4d2D3/2,5/2 transitions along the copper isoelectronic sequence. Core polarisation effects are included in a relativistic Hartree-Fock method as well as in a relativistic semi-empirical model-potential approach by introducing a core polarisation potential in the calculation of wavefunctions and by employing the corresponding correction for the dipole moment operator in the transition matrix element. The results obtained are compared with available theoretical and experimental data and the influence of core polarisation effects is discussed.
