| 英文摘要 | Van der Waals clusters are weakly bound atomic/molecular systems and are an important medium for understanding micro-environmental chemical phenomena in bio-systems. The presence of neighboring atoms may open channels otherwise forbidden in isolated atoms/molecules. In hydrogen-bond clusters, proton transfer plays a crucial role, which involves mass and charge migration over large distances within the cluster and results in its fragmentation. Here we report an exotic transfer channel involving a heavy N+ ion observed in a doubly charged cluster produced by 1MeV Ne8+ ions: (N2Ar)(2+)-> N++NAr+. The neighboring Ar atom decreases the N22+ barrier height and width, resulting in significant shorter lifetimes of the metastable molecular ion state N22+(X1 Sigma g+). Consequently, the breakup of the covalent N+-N+ bond, the tunneling out of the N+ ion from the N22+ potential well, as well as the formation of an N-Ar+ bound system take place almost simultaneously, resulting in a Coulomb explosion of N+ and NAr+ ion pairs. There are multiple ways by which energy and charge transfer occur in weakly bound systems. Here the authors reveal a heavy ion N+ transfer in a doubly charged Van der Waals cluster produced in collisions of the highly charged Ne8+ ion with N2Ar, leading to fragmentation of N+ and NAr+ via Coulomb explosion. |
