Abstract
Term values and ionization potentials have been calculated for several ions in the promethium ( N = 61) isoelectronic sequence. As the nuclear charge is increased, the ground configuration changes from 4f 135s 2 to 4f 145s giving the upper portion of the sequence an alkali-like character. According to our most recent Hartree-Fock calculations with first-order relativistic corrections, the ground term is 5s 2S for Z > 77 (Ir XVII) and the first excited term is 5p 2P 0 for Z > 84 (P 0 XXIV). Comparisons are made with calculations of Cowan in W XIV. The prospects for observation of these spectra in fast ion beams are discussed.
