Classical trajectory calculations were performed for the collision of xenon atoms with van der Waals dimers of chlorine molecules. Experimental results indicate that much more energy than required for dissociation of the dimer bond is deposited in the molecular vibrations in such processes without disrupting the complex. No energy transfer to the molecular bonds was observed for the trajectory studies, but energy was transferred to van der Waals modes. No long-lived clusters were found in which the energy transfer exceeded the van der Waals well depth. The energy threshold for collision induced dissociation was found to be roughly equal to the van der Waals well depth, in contrast to the large thresholds reported for the molecular beam experiments. It is suggested that possibly the commonly accepted values for the depth of the van der Waals wells in chlorine dimers are too small.
