Study of Multicapture Cross Sections Using Multicoincidence Technique in Xe30+ on C60 Collisions

Abstract

We have performed a multicoincidence experiment between electrons, recoil ions and projectile final charge states for HCI-C60 collisions. Three regimes of interaction were studied depending on impact parameter. Atom-like, surface-like and solid-like interactions could be well separated by the measurement of the final charge state of projectile and the electron multiplicity spectra. We investigated hollow atoms formed in Atoms-like interaction by estimating the kinetic energies of ejected electrons in free interaction region (after the collision). The projectile kinetic energy analysis allowed separation of the surface-like from the solid-like interactions. In the surface-like interaction, the average stabilization time of one electron has been estimated from the number of ejected electrons during the interaction time and found equal to about 0. 5 fs. This very low value shows that the stabilization of electrons in hollow atoms prepared by such collisions is very fast.
