Equilibrium size distribution function of clusters in finite system

Abstract

The equilibrium size distribution function of clusters (nanoparticles) in the system of finite number of molecules (atoms) in finite closed volume with constant total energy (isolated system) is found using methods of statistical thermodynamics. The distribution function is found from kinetic equation of nucleation using one-drop approximation for both isothermal and isolated systems. The results obtained are compared with computer simulation data of finite two-dimensional system.
