Abstract
Cross sections for single and multiple ionization of the target atom with simultaneous ionization of the projectile have been measured for 1-4 MeV collisions of He+ with Ne. The observations are interpreted using the n-body classical trajectory Monte Carlo method. The 11-body calculations include the L-shell electrons of the Ne and the K-shell electron on the He+. In this model, each electron interacts with both nuclei and with all the electrons belonging to the other centre. For single ionization from both centres, it is found that the dynamical electron-electron (e-e) interaction produces a clear signature in the relative azimuthal angle distribution between the ionized electrons. For low values of momentum transfer q, this interaction is reflected in a pronounced enhancement near 180° in the azimuthal angle between electrons. Integral values of the azimuthal angle events, summed over all q values, indicate that it is possible to determine the relative importance of the e-e versus the nuclear-electron (N-e) interactions.
