Abstract
The UK molecular R-matrix codes are used to study electron collisions with the He+2 molecular ion. Full configuration interaction calculations are performed to obtain the potential energy curves of the ground X 2Σ+u and the first excited 2Σ+g electronic states of He+2. Resonances, effective quantum numbers, and resonance widths as a function of the internuclear separation are determined for the lowest singlet 1Σ+g, 1Σ+u, 1Πg and 1Πu and triplet 3Σ+g, 3Σ+u, 3Πg, 3Πu and 3Δu states, which are relevant for the study of the reactive collision of He+2 with low-energy electrons. In addition, bound states are also calculated for each symmetry of He2 at several geometries.
