The 3p(6)3d(7)-3p(5)3d(8) transitions of manganese-like spectra Rb XIII and Sr XIV

Spectra of Rb XIII and Sr XIV have been studied in the region from 80 to 11 0 Angstrom by means of a triggered spark and a 3m-grazing incidence spectro graph equipped with a 3600 lines/mm holographic grating. Sixty-two lines in Sr XIV and 105 lines in Rb XIII are used to derive energy levels of the gr ound configuration 3p(6)3d(7) and of the first excited odd parity configura tion 3p(5)3d(8). A parametric study by means of the chain of Cowan codes st resses the importance of configuration interactions (C.I.) within the Layze r complexes (3)(15). Both the effective electrostatic C.I. parameters and t he full complex treatment lead to a reduction of the large residual deviati ons noticed in earlier studies of 3p(5)3d(8) configurations of the sequence Y XV-Mo XVIII. Theoretical transition probabilities are reported for all c lassified lines.
