Blue satellite structure of the Ba resonance line broadened by rare gases

Interaction potentials and transport properties of Ba, Ba+, and Ba2+ in rare gases from He to Xe

A highly accurate, consistent set of ab initio interaction potentials is obtained for the title systems at the coupled cluster with singles, doubles, and non-iterative triples level of theory with extrapolation to the complete basis set limit. These potentials are shown to be more reliable than the previous potentials based on their long-range behavior, equilibrium properties, collision cross sections, and transport properties.
