Electron transfer, excitation, and ionization in p -H ( 1 s ) collisions studied with Sturmian bases

摘要: Cross sections have been determined for electron transfer, direct excitation, and ionization in collisions between protons $\text{H}(1s)$ atoms at proton energies from 1 keV to 16 MeV, extending the pioneering work by Shakeshaft [R. Shakeshaft, Phys. Rev. A 14, 1626 (1976); 18, 1930 (1978)] with a much smaller basis energy range, following author's other collisional systems [T. G. Winter, 76, 062702 (2007)]. Transfer as well excitation cross into individual states up $3d$ (excitation $4f$ higher energies) several coupled-Sturmian-pseudostate bases, tests of sensitivity carried out. These compared experimental, coupled-state, numerical results. Ionization also corresponding Born results energies.
