✦ Synopsis
Collisions of highly anharmonic, weakly bound quantum clusters with atoms and molecules were studied by time-dependent calculations. Collinear collision models were assumed, and systems studied included (H,),, (D2)2, B-H*, (H2)3, (D,), in encounters with Li atoms or Hz molecules. Substantial survival probabilities of the clusters were found, even for collision energies which exceed the cluster binding energy by orders of magnitude. The results are interpreted in terms of the vibrational wavefunction of the target cluster, which gives a relatively low weight for the configurations most favorable for collision induced dissociation.
