Single electron capture differential cross section in H++Hecollisions at intermediate and high collision energies

The generalized continuum distorted wave-eikonal initial state (CDW-EIS 11) approximation is employed to study differential cross sections (DCS) for single electron capture in H+ + He collisions at intermediate and high energies. Present results are compared with theoretical calculations obtained using the previous CDW-EIS formulation in order to show the importance of the description of the bound and continuum target states in the entrance and exit channels, respectively. Both DCS are also shown together with other theoretical results and with experimental data.
