Oscillator strengths in the Mg isoelectronic sequence.
Abstract
Calculations of boundbound oscillator strengths for the Mg isoelectronic series from Mg through Cl(5+) are presented which were performed using a semiempirical model potential method. Approximate solutions to a model Schroedinger equation for the valence electrons are obtained for the lowest four states of several S, P, and D symmetries; the oscillator strengths for all dipoleallowed transitions are computed from these wave functions. A comparison of the present oscillator strengths with available theoretical and experimental data shows excellent agreement in most cases. The few substantial discrepancies between some results are attributed to uncertainties in the experimental data.
