Application to ab initio calculations to nuclear internal conversion: repulsion energies of highly charged HBr ions

Ab initio MO calculations were applied to the evaluation of repulsion energies in highly charged HBr ions. Net charges of H and Br atoms were obtained from the Mulliken atomic population, and repulsion energies were estimated by a simplified model based on the Coulomb repulsion. The repulsion energy of HBr8+ was calculated to be 71.5 eV. (Auth.)
