A Mixed Quantum/Classical Approach to Associative Detachment in Low-Energy H– + H Collisions

International audience; A theoretical approach, in which the rotational degrees of freedom are treated quantum mechanically while translational degrees of freedom classically or semiclassically, is applied to calculate the total and final-state specific cross sections for the reaction H − + H → H 2 (v, j) + e − in the range of low collision energies (E = 1− 754 meV). The calculated cross sections agree well with the existing experimental and theoretical results. Results are also presented for the inverse dissociative attachment process: H 2 (v, j) + e − → H − + H.
