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 cluste

✦ Synopsis
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 the absence of such stable clusters for argon is due to the dispersion forces that result from triple-dipole interactions.

We report a rapid increase in the propensity of D,O molecules to incorporate into (H,O); clusters upon collisions between D,O and a distribution of (H\*O);, 6< n c 25, clusters. We interpret this effect by invoking a size-dependent associative electron detachment cross section which increases rapidl
