Scientific paper

Using the computer program SUPERSTRUCTURE, M1 and E2 transition probabilities have been calculated between the 3p(6)4s 2S(1/2) and the 3p(6)3d 2D(3/2), 2D(5/2) levels in the first six members of the potassium isoelectronic sequence. A two-step minimization procedure and semiempirical term-energy corrections have been included in the present calculations, which is based on a comparatively simple physical model. The data thus obtained compare well with the recent findings of Ali and Kim (1988), who used the multiconfiguration Dirac-Fock (MCDF) formalism. Particular attention is paid to the case of Ca(+) because of its astrophysical importance.
