Transition probabilities for forbidden lines in the ground-state configuration of the bromine isoelectronic sequence

Calculations of transition probabilities are reported for the magnetic dipole and electric quadrupole components of the ground-state transition in the 4p5 configuration of the bromine sequence up to Xe XX. The relativistic Hartree-Fock (HFR) self-consistent-field method was used combined with parametric fitting in a configuration interaction approach. The results reported here are an extension of similar calculations recently reported in 3pN and 4pN configurations, and some comments on the effect of 3p → 4f excitations in 3p1 and 3p5 configurations are given together with a discussion of the relative merits of the HFR and HXR methods for the calculation of spin-orbit integrals.
