Résumé :

The close-coupling method based on semiclassical impact parameter theory has been applied to p + Be3+ collisions in the range of proton impact energies from 30 keV through to 10 MeV. The cross sections for hydrogen production, target excitation and ionization have been computed using two-centre AO expansions with up to 55 atomic states and pseudostates. The results can be used as reference data for further close-coupling studies of the system as well as for assessing the validity range and accuracy of various perturbational models at both intermediate and high energies. Applications to current plasma research at JET where accurate data are required for diagnostic purposes, are discussed.
