Abstract
Coupled Hartree-Fock theory is used here to calculate the frequency-dependent dipole and quadrupole polarisabilities of Be, B+ and C2+ in their ground states 1S. Particular emphasis is given to obtaining the excitation energies and the transition oscillator strengths for some low-lying excited states. The oscillator strengths are in very good agreement with those of more elaborate configuration-interaction calculations.Keywords
