Abstract
A model calculation has been made of the effects of perturbations of the series of aluminum by the term. The model employed is the traditional one of configuration interaction among the independent-particle model representations of the relevant discrete states, with Hartree-Fock functions being used to compute the necessary matrix elements. It is found that, while in the Hartree-Fock approximation the term is bound and embedded in the series, the configuration interaction gives rise to a new autoionizing state just beyond the series limit. This state, which is approximately 50% , is found to have most of the absorption oscillator strength (). The general properties of this model of series perturbations are also discussed in some detail.
