Magnetic-Dipole and Electric-Quadrupole Transitions in the Ground-State Configurations of the Germanium and Arsenic Isoelectronic Sequences

Abstract

Calculations of energies and transition probabilities are reported for forbidden lines in the ground configurations of the germanium (4p2) and arsenic (4p3) isoelectronic sequences up to silver (Z = 47). Configuration interaction and relativistic effects were included in the framework of the HXR and HFR self-consistent-field methods. Transition probabilities have been obtained in intermediate coupling using parameter values for the 4p2 and 4p3 configurations obtained either by fitting or by extra-(inter)polation when experimental energy levels are missing. Except for Ge I and As I, transition probabilities are reported for the first time for all these ions.
