Wavefunctions and oscillator strengths of the beryllium iso-electronic sequence

Abstract

Configuration interaction wavefunctions for the 1s22s2 1S, 1s22s2p 3P and 1s22s2p 1P states are calculated for Be I, B II, C III, N IV, O V, F VI and Ne VII and are used to calculate oscillator strengths for the 1S to 1P transition.
