Abstract
Two hundred and ninety-five lines of the spectra of cobalt-like ions Y XII, Zr XIV, Nb XV, Mo XVI, Ru XVIII, Rh XIX, Pd XX and Ag XXI have been classified as 3d9-3d84p transitions. They involve 250 energy levels which are described by 21 parameters with a root-mean-square deviation of 290 cm-1. The scaling factors of radial integrals calculated by the Hartree-Fock method have been fitted as well as effective electrostatic parameters. The validity of the results is based on isoelectronic regularities and has been checked by extrapolations to the known spectra of Br IX and Sn XXIV. Predictions are given for Kr X, Rb XI, Sr XII, Cd XXII and In XXIII.Keywords
