Semi-classical Computation of Low-energy Collisions Cross Section in Mutual Neutralization of Helium and Hydrogen Ions

Abstract

A Semi-classical model is employed to theoretically study mutual neutralization in the collisions of 4 He + and H − . The model includes nine covalent states of 2 Σ + symmetry. Here the assumption is that only two states are interacting at a given internuclear position. The reaction is studied for collisions energies below 100 eV . The total mutual neutralisation cross section is computed and compared with previous results.
