Abstract
The authors calculated oscillator strengths for the principal series of the alkali atoms Li, Na and K from the g-Hartree equation. A mean field optimised by the procedure described in earlier publications is shown to yield a rapidly convergent expansion of the remaining correlation effects: the zero order already yields a substantial improvement over HF and DHF calculations and gives good agreement with experiment. It is noteworthy that the optimised g-Hartree single-particle potential for the excited states interpolates between purely V(N) and V(N-1) potentials.Keywords
