Popis: High-resolution Br MVV Auger spectra of HBr and DBr have been recorded using monochromatized synchrotron radiation. We present a detailed analysis and reassignment of the spectra in the 3d-1->4p?-2 region. This part of the spectra exhibits the spin-orbit and ligand-field splitting of the 3d-1 core-hole states and a vibrational structure of the final states influenced by vibrational lifetime interference. The equilibrium distances and the vibrational energies of the final states 1?+, 1?, and 3?- are derived from the intensity distribution of the vibrational substates. From the shape of the peaks identified as transitions to the 3?- state a splitting of ?50 meV between the components 3?0- and 3?1- is concluded. Agreement between the experimental spectra and fitted results for both HBr and DBr is very satisfactory.
