Abstract
Within the framework of the cluster model of the structure of disordered condensed media, using the pair potential of Mie interaction with the effective depth of the potential well, the relation was obtained for calculating the heat of sublimation of small cluster systems containing up to 500 particles. It is shown that the heat of sublimation of small clusters, referred to the energy of pair interaction between particles, is a universal function of the number of particles in the cluster system, which can be mathematically represented as the square of the hyperbolic tangent. The proposed model makes it possible to estimate the potential energy of the global minimum of the cluster system.
