Abstract
Differential cross sections for charge-exchange and single and double electronic emission in collisions of protons with He atoms at intermediate impact energies are theoretically evaluated by means of two classical trajectory Monte Carlo methods. These models incorporate momentum-dependent terms to the Hamiltonian in order to avoid the classical autoionization of He. The theoretical results for single capture and single ionization are compared to available experimental data. The role of the electron–electron correlation effects in double ionization processes is analyzed by inspecting the angular and energetic dependence of the electronic emission spectra at different impact energies.
