Variance of the distributions of energy levels and of the transition arrays in atomic spectra. II. Configurations with more than two open subshells

Abstract

In a previous article it has been shown how the variance of the distribution of the lines belonging to a transition array between two atomic configurations can be computed exactly. The agreement with experimental unresolved spectral patterns was good. We generalize the formal expansions obtained previously for simple arrays to cases with an arbitrary number of open subshells. The results are expressed in terms of the formulas already published [Phys. Rev. A 20, 2424 (1979)].
