Abstract
A method is developed for calculation of single-particle occupation nu mbers in finite Fermi systems of interacting particles. It is more acc urate than the canonical distribution method and gives the Fermi-Dirac distribution in the limit of large number of particles. It is shown t hat statistical effects of the interaction are absorbed by an increase of the effective temperature. Criteria for quantum chaos and statisti cal equilibrium are considered. All results are confirmed by numerical experiments in the two-body random interaction model.
