Shaking during Ion-Atom Collisions

TL;DR

This paper investigates shaking probabilities during ion-atom collisions, emphasizing the impact of collision suddenness over recoil velocity, using hydrogenic wavefunctions within the sudden approximation.

Contribution

It introduces a detailed analysis of shaking processes in ion-atom collisions considering the collision suddenness and recoil effects, expanding understanding of atomic electron behavior during such events.

Findings

Collision suddenness significantly influences shaking probabilities.

Recoil velocity has a lesser effect compared to collision suddenness.

Shaking probabilities vary across K-, L-, M-shell electrons.

Abstract

Shaking (shakeup + shakeoff) probabilities accompanying ion-atom collisions are studied using hydrogenic wavefunctions for K-, L-, M- shell electrons in the sudden approximation limit. The role of recoil velocity in the shaking processes is discussed. Further, it is found that the suddenness of collision between projectile and target nuclei plays a major factor in shaking of respective atomic system than the recoil of nuclei.
