Description

Abstract Recent years have seen an increasing demand on accurate transition probability calculations for open-shell atoms and ions. To facilitate such investigations, the program REOS [S. Fritzsche, C.F. Fischer, Comput. Phys. Commun. 99 (1997) 323] has been developed which includes the effects of relativity, correlation, and the rearrangement of the bound-state electron density within the framework of the multiconfiguration Dirac–Fock model. Often, however, very large wave function expansions are ind... Title of program: REOS99 Catalogue Id: ADEJ_v2_0 [ADLF] Nature of problem Transition probability calculations for (open-shell) atoms have shown that large wave function expansions are often needed to obtain sufficient accurate results. For ab-initio calculations, these wave functions must include the effects of relativity, electron correlations, and the rearrangement of the electron density within a common framework. The REOS99 program accounts for all of these effects for the computation of Einstein coefficients, oscillator strengths, and (radiative) lifetimes. It ap ...
