COLLECTIVE EFFECTS IN THE DESORPTION PROCESS INDUCED BY Hn+ CLUSTERS NEAR THE BOHR'S VELOCITY

Abstract : The emission yield of the positive ions Cs+ and H+ from CsI bombarded by 600 keV Hn+ clusters, has been correlated with the energy deposited by these particles. Above the BOHR'S velocity, vo, the concept of equipartition between close and distant collisions could apply while below vo, collective effects are still observed (distant collisions). The same power relationship between the emission yield and an "efficent" mean stopping power for the cluster is pointed out within the whole investigated velocity range.
