Electron transfer, ionization, and excitation in collisions between protons and the ions He$^+$, Li$^{2+}$, Be$^{3+}$, B$^{4+}$, and C$^{5+}$

Coupled-state cross sections have been determined for electron transfer, ionization, and excitation in collisions between keV-energy protons and the hydrogenic ions He$^{+}$, Li$^{2+}$, Be$^{3+}$, B$^{4+}$, and C$^{5+}$,\footnote{T. G. Winter, Phys. Rev. A (in preparation).} extending work reported 26 years ago with a limited basis for electron transfer and ionization only\footnote{T. G. Winter, Phys. Rev. A {\bf 35}, 3799 (1987).}; the C$^{5+}$ process was also considered in a later study.\footnote{T. G. Winter, Phys. Rev. A {\bf 56}, 2903 (1997).} In the present calculation, a basis of 60 Sturmians on each center has been used, and in a second calculation, a basis of 280 Sturmians on the target nucleus and a single $1s$ function on the proton, with greater overall accuracy than the previously published results. Further, cross sections for direct excitation and capture to individual excited states up to $3d$ have been determined. The extent to which high-energy scaling rules with target nuclear charge $Z$ are valid has been re-examined for transfer to the ground state, total transfer, and ionization, and is now considered also for excitation and individual-state processes at intermediate energies near where the cross sections peak.
