The process of mutual neutralization of and H - ions in the CM collision energy range is studied within the multi-channel Landau-Zener model. From the multitude of covalent states only the states , and are strongly coupled with the initial ionic state. The total mutual-neutralization cross-section has a broad maximum around of about , and below it monotonically increases with decreasing the collision energy, surpassing a value of below . The mutual neutralization of and H - ions is, therefore, an important process in cold hydrogen plasmas.
