Abstract
Oscillator strengths for dipole transitions between 1s 23s 2S, 1s 23p 2P and 1s 23d 2D states of the lithium isoelectronic sequence in the L-S coupling scheme have been calculated in the Hartree-Fock approximation by perturbation theory through the use of Dalgarno's interchange theorem. The results compare very favourably with the analytical Hartree-Fock results.Keywords
