Abstract
We report the direct observation of the multi-ionization of the H-21() hydrogen cluster in a single collision with a helium atom at 60 keV/ u. Up to quadruple ionization of the cluster was observed and new mult i-fragmentation channels were detected. Moreover, the results show two different fragmentation processes of doubly charged H-21(2+) clusters : emission of an H-2(+) dimer, or emission of an H-3(+) trimer after r earrangement in the cluster prior to fragmentation.
