Relating the 4s σ^-1 inner-valence photoelectron spectrum of HBr with the Br 3d^-15lλ resonant Auger spectra: An approach to the assignments

The high-intensity, high-resolution Br4sσ^-1 photoelectron spectrum, and the resonant Auger spectra resulting from excitation of the Br 3d level to low Rydberg states are presented. By relating these spectra to each other, most of the lines in these spectra are assigned to different symmetry states with small vibrational components without support of theoretical predictions. Fortunately, vibrational effects are very small in these resonant Auger spectra as well as in the 3d photoabsorption and photoelectron spectra.
