摘要：

Cross sections for one-electron capture, excitation and ionization in proton-oxygen collisions are calculated by the two-centre atomic orbital expansion close-coupling method. The transition probabilities are constructed from a one-electron independent-particle approximation. The electronic states in oxygen are represented by orbitals obtained from an analytical model potential with parameters fitted to the Hartree potential of the ground state configuration. Capture cross sections are dominated by the 2p electrons and are in very good agreement with measurements.
