A new strategy for the calculation of the CI oscillator strengths for the lowest lying autoionizing level in the Na isoelectronic sequence

Abstract

We report Hartree-Fock and configuration-interaction calculations of both the length and velocity forms of the oscillator strengths for the resonance excitation 1s{sup 2}2s{sup 2}2p{sup 6}3s{sup 2}S{sup e}{sub j} {yields} 1s{sup 2}2s{sup 2}2p{sup 5}3s{sup 2} {sup 2}P{sup u}{sub j} transition, which leads to autoionization (Auger transition), in several ions of the sodium isoelectronic sequence both in LS and intermediate coupling schemes employing a new strategy. The method is computationally economical and capable of yielding encouraging results. (author). 5 refs, 1 fig., 5 tabs.
