REOS — A program for relaxed-orbital oscillator strength calculations

摘要: Abstract A spontaneous decay of an excited atomic state leads to a rearrangement the spatial electron distribution in atom. This redistribution concerns entire electronic cloud and not only active transition. For many-electron atoms, effects are naturally included if wavefunctions initial final states determined independently. The separate optimization states, however, yields two sets one-electron orbitals which orthogonal each other. incomplete orthogonality also influences calculation transition amplitudes since, additionally, many small contributions arise from radial overlap electrons different subshells have same symmetry. In framework GRASP92 structure package we describe program for computation oscillator strengths Einstein B coefficients. is based on determinant representation allows orbital functions states. large lists configuration functions, this module facilitates arrays since need be run.
