Regularities in the distribution of oscillator strengths of lines in spectra of group II atoms: BeI, MgI, and CaI

Abstract

Regularities in the distribution of oscillator strengths of lines in spectra of II group atoms of the periodic table of elements BeI, MgI, and CaI are established. It is established that the linear dependence described the oscillator strengths of transitions, for which the principal quantum numbers of the upper and lower states are simultaneously changed by unity. For BeI, MgI, and CaI atoms 98 linear dependencies having a high correlation coefficient (as a rule R > 0.99) were established. It is shown the influence configuration interaction on being linear dependencies. © 1997 Elsevier Science Ltd. All rights reserved. † To whom all correspondence should be addressed.
