Abstract
Closed-form expressions for 1s-1s electron-capture amplitudes for +H collisions in three different approximations are compared. We find that all three approximations agree well in the region of the Thomas peak, but significant differences are noted at the minimum in the angular distributions of scattered neutral hydrogen atoms.
