Surface entropy of rare-gas clusters

Abundances of Ar N + and Xe N + clusters produced in a supersonic expansion source are inverted to find relative dissociation energies. The values around the shell and subshell closings at N = 55 , 71, and 147 differ from theoretical values derived from ground-state energies of Lennard-Jones cluster...

Description
Summary:Abundances of Ar N + and Xe N + clusters produced in a supersonic expansion source are inverted to find relative dissociation energies. The values around the shell and subshell closings at N = 55 , 71, and 147 differ from theoretical values derived from ground-state energies of Lennard-Jones clusters. A significant part of the difference can be accounted for by the conformational entropies of surface atoms and vacancies.
