摘要

The collision-induced multifragmentation of Na_4~+ alkali metal culster ions by He impact in the 100 eV (center of mass0collision energy range is investigated theorectically using a DIM-based nonadiabatic molecular dynamics method.Campared to our earlier adiabatic molecular dynamics calculations new fragmentation channels are populated and new relaxation processes of excited electronic states to the ground state take place.The mechanisms of the different processes are anzlyzed.Comparisons with experiments are presented and discussed.
