Non-convoy electron emission in ion-metal surface collisions at grazing incidence

摘要

In this work we calculate the electron emission due to the process of electron loss to the continuum by the projectile in fast grazing incidence ion-metal collisions. The combined effect of the projectile nucleus, its induced image charge and the surface potential on the emitted electron, is included starting from the calculated continuum wave function via the enhancement factor. We will call this model the Surface Continuum Distorted Wave (SCDW) Model. The electron emission predicted by the SCDW model, even when in this first calculation we only include the electron loss effect, describes the position of the peak and the relative intensities for higher observation angles.
