Abstract: Based on statistical approach we described possible formation of spatiallyinhomogeneous distribution in the system of interacting Fermi particles bylong-rage forces, and we demonstrated nonperturbative calculation of thepartition function in this case. It was shown, that particles interacting withan attractive $1-r$ potential form clusters. Cluster is equilibrium structure,if we suppose that average energy of interaction of two particles is much lessthan their average kinetic energy $kT$. The analogy between self-gravitationgas and plasma was shown. The dynamics of cluster formation was considered withhelp hydrodynamical and statistical approaches, and time of relaxation toequilibrium state was found.
