Transfer and excitation in ion-atom collisions at high impact velocities: a unified continuum distorted wave treatment of resonant and non-resonant modes in a four-body approach. II. Application to the collision S¹⁵⁺(1s)+H(1s)

For pt.I see ibid., vol.25, no.4, p.825-37 (1992). Resonant (RTE) and non-resonant (NTE) transfer and excitation processes which occur in collisions of fast S15+ (1s) with H atomic targets, are investigated through a four-body continuum distorted wave approximation (CDW-4B) derived by Gayet and Hanssen (1992). The present application is a test of this new theoretical unified approach. Results are compared with previous theoretical and experimental data obtained with molecular targets for impact energies close to resonances. A first quantitative study of the interference between the two coherent processes is made using a model in which both the projectile and the target are hydrogen-like ions. For inner-shell capture from targets whose nuclear charge is comparable with the charge of the projectile, it is shown that interference effects might be significant, even at impact energies close to resonances.
