چکیده    Big clusters of tin snn (so called mesoscopic particles) containing hundreds of atoms with diameter up to 15 nm show that cohesion of mesoscopic particles results from local interactions between nearest neighbor atoms. many body interactions play only a minor role. using semi-empirical calculation, we were able to build a growth models for tin particles. the criteria for the best model is determined by structure of particles, localization of interactions and mainly the values of the binding energies and internuclear distances and their convergence to cluster particles of the bulk.
