Singly differential cross sections for direct scattering, electron capture, and ionization in proton-hydrogen collisions

We use the two-center wave-packet convergent close-coupling approach to calculate singly differential cross sections for direct scattering, electron capture, and ionization in proton-hydrogen collisions at intermediate energies. The distinct feature of the approach is that it gives a complete differential picture of all the interconnected processes at once, subject to the unitary principle. Results obtained for the angular differential cross sections of elastic scattering, excitation, and electron capture, as well as the ionization cross sections differential in the ejected-electron angle, and in the ejected-electron energy agree well with available experimental data. It is concluded that the two-center wave-packet convergent close-coupling approach is capable of providing a realistic differential picture of all collision processes taking place in proton-hydrogen collisions.
