What is On a Screening Theory of Atomic Spectra about?
A theoretical scheme for describing atomic spectra is developed. It differs from the current one in three main ways. (i) The nuclear charge 2 enters explicitly into all predictions made with the new scheme. (ii) Certain effects of configuration interaction are allowed for in the first approximation. Spectroscopic terms are no longer assigned to definite configurations in the first approximation, but rather to more comprehensive aggregates called complexes, specified by a set of radial quantum numbers and a definite value of the parity. (iii) The notion of screening takes on a precise quantitative meaning, and the predictions of the theory are expressed largely in terms of screening parameters. The new scheme is simpler than the one based on the central-field approximation and Hartree-Fock wave functions, and in some ways at least it is also more accurate. For example, its predictions concerning relative term energies are free of the large systematic discrepancies that show up when the current theory is used to describe term spectra.
