H(2s) formation and Lyman-. cap alpha. polarization in 1--7-keV H/sup +/-H collisions

Journal Article · · Phys. Rev. Lett.; (United States)

A multistate molecular approach to the proton--hydrogen-atom collision is formulated. Spurious long-range couplings are avoided and Galilean invariance enforced through variationally determined momentum translation factors. Well-defined radial and rotational couplings are employed in the 1--7-keV energy range in a ten-state calculation. Good agreement with Bayfield is obtained for the 2s charge-exchange probability. Concerning polarization of Lyman-..cap alpha.. radiation, comparison with Kauppila et al. is made.
