Resumen:
A study of the autoionization process induced by partially stripped ion impact is performed. Electron spectra
in momentum space are predicted within a classical model for partially stripped ions. The results are compared
with those obtained for pure Coulomb-like projectiles. A quantum-mechanical extension of the Barrachina-
Macek model is proposed for partially stripped projectiles. Structure on the electron angular distribution arising
in quantum and classical treatments is identified and compared. The presence of rainbow scattering interference
is observed in the binary ring profile of the outgoing autoionized electrons for positive-ion impact.
