R-matrix calculation of bound and resonant states of BeH

Bound and resonant states of BeH are studied using the diatomic UK molecular R-matrix codes together with a Slater basis set for the BeH⁺ target states. Bound and resonant states of BeH are determined from an e-BeH⁺ collisional calculation. The calculations are repeated for 40 internuclear distances in the range 1.5–6.0 a ₀ to yield bound state and resonance curves for BeH. Additionally, we also obtain the resonance widths in the range of the inter-nuclear distances considered. The data obtained may be useful for modeling various e-BeH⁺ collision-induced processes, particularly dissociative recombination and dissociative excitation. (paper)
