Autoionization of He atoms induced by partially stripped ion impact

A study of the autoionization process induced by partially stripped ion impact is performed. The Barrachina-Macek model is extended to the case in which the projectile-emitted electron interaction is represented by means of a non-Coulombic central potential at all times. Electron spectra in momentum...

Descrição
Resumo:A study of the autoionization process induced by partially stripped ion impact is performed. The Barrachina-Macek model is extended to the case in which the projectile-emitted electron interaction is represented by means of a non-Coulombic central potential at all times. Electron spectra in momentum space are predicted and compared to the Barrachina-Macek model and a recent model in which an asymptotically correct wave function was employed to treat this problem. The presence of rainbow scattering interference in the binary ring profile of the outgoing autoionized electrons for positive ion impact is discussed based on the different models.
