Single- and double-electron charge transfer in collisions of α-particles with hydrogen molecules. II.

Dependences of single-electron charge transfer cross sections on the molecule orientation are studied in collisions between α-particles and H molecules in the ground state at collision energies E from 1 to 23 keV/u. Probabilities of single-electron capture were calculated in the independent electron approximation in the context of the close coupling equation method under the assumption that the hydrogen molecule consists of two independent hydrogen pseudoatoms. The total and partial single-electron capture cross sections averaged over all orientations of the molecule well agree with available experimental data at E > 5 keV/u. [ABSTRACT FROM AUTHOR]
