Resumen:
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 bymeans of a non-Coulombic central potential at all times. Electron spectra in momentum space are predicted andcompared to the Barrachina-Macek model and a recent model in which an asymptotically correct wave functionwas employed to treat this problem. The presence of rainbow scattering interference in the binary ring profileof the outgoing autoionized electrons for positive ion impact is discussed based on the different models.
