Semi-classical Computation of Low-energy Collisions Cross Section in Mutual Neutralization of Helium and Hydrogen Ions
A Semi-classical model is employed to theoretically study mutual neutralization in the collisions of $\mathrm{^4He^+}$ and $\mathrm{H^-}$. The model includes nine covalent states of $\mathrm{^2Σ^+}$ 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
