The use of static potentials in atomic collisions. Application to the excitation of hydrogen atoms by helium ions at intermediate energies
Year: 1983
Type: article
Abstract: A model based on the independent-electron approximation and the impact parameter formalism has been developed, in order to take into account the influence of passive electrons in collisions between multielectron ion(atom) projectiles and monoelectron ion (atom) targets, and where only the electron in the target is active. Differential cross sections for excitation to the n=2 states of hydrogen by He + impact, in the intermediate energy region, are calculated as an application of this model. A reasonable agreement with recent experimental data is obtained using a two-state atomic expansion. The negligible influence of the He(1s, 2p +or-1 ) capture state on the excitation processes has been determined.
