✦ Synopsis

We present in this Letter the observation of a magic number of n = 4 in the (C, H4) ,$ cluster ion distribution only under experimental conditions of low nozzle temperature or high stagnation pressure. We attribute this result not to any special thermodynamic stability of the neutral or ionic cluster, and speculate that it is due to the formation of a CsH:6 molecular ion. We suggest that this product cation is formed via a series of exoergic condensation reactions which occur within the parent ethene cluster ion. Also presented are pressure dependence data which are used to elucidate other competing reactive mechanisms.

The formation of clusters in compressed arson and xenon gases is studied with the molecular dynamics simularion technique using two-body Lennard-Jones and three-body Axilrod-Teller potentials. It is suggested that the occurrence of clusters corresponding to the "magic number"~~ = 13 for henon and th
