摘要：

The most abundant decay channels have been studied quantitatively for high-energy (60 keV/amu) cluster ions H-3(+)(H-2)(m=1-14) colliding with He atoms employing a recently developed multicoincidence technique for the simultaneous detection of the correlated fragments on an event-by-event basis. This allows us to identify decay reactions and their underlying decay mechanisms responsible for the occurrence of the U-shaped fragmentation pattern.
