Abstract

The cross sections and reaction rates for the associative detachment reaction Li + H⁻ → LiH + e⁻ are calculated for energies from 1 meV to 1 eV within the nonlocal discrete-state-in-continuum model. The nonlocal model yields stable results for this nonadiabatic process although there is no obvious curve crossing of the ground anion state into the continuum in adiabatic approximation.
