Auger decay widths of the ligand-field-split Br 3d components in the HBr molecule

In this paper, high resolution Br 3d photoelectron spectra of HBr are presented. Experimental lifetime widths of the ligand-field-split Br 3d components have been derived, and compared with theoretical predictions based on the one-centre approximation accounting for relativistic effects. The dependence of the theoretical decay widths on the kinetic energy for the Auger electron and the correlation in the final states of the Auger decay has also been investigated.
