Semi-classical Landau-Zener studies of mutual neutralization reactions in low-energy H+ + H- and Be+ + H- collisions are performed. Avoided crossings between ionic and covalent states occurring at large internuclear distances are considered, and electronic couplings between these states are estimated using different semi-empirical and ab initio methods and tested on the H+ + H- reaction. The method is then applied to compute the cross sections and final state distributions for mutual neutralization in collisions of H- with Be+. These are reactions that might be important for the modeling of the fusion edge plasma of the divertor of ITER.
