Synopsis We develop a two-center wave-packet convergent close-coupling approach to proton collisions with helium including electron exchange. The convergence of the final results is studied in terms of the included projectile- and target-centered pseudostates. We present electron-capture and single- and double-ionisation cross sections in the projectile energy range from 15 keV to 1 MeV. We also provide partial cross sections for electron capture and direct excitation into the n = 2 shell states of hydrogen and helium, where n is the principal quantum number of the final state. Our results are in good agreement with available experimental data and other calculations.
