Rotation/translation interplay in the recoil statistics of cluster evaporation

A new statistical model has been developed in the framework of Phase Space Theory to describe the evaporation process of non-rotating clusters. The no velty of the theoretical approach resides in its ability to easily separate the total kinetic energy released in an evaporation process into the rotat ional and translational contributions. This new model has been tested by co mparing its predictions with the results of Molecular Dynamics (MD) simulat ions for the unimolecular evaporation of two types of van der Waals cluster s: the aniline-(argon)(n) molecular clusters and the neat argon Ar-n cluste rs.
