Abstract
Using the theory of groups the many-particle average of the product of one-body operators is determined in terms of the one-body average of the products of these operators. With this all the energy moments of the noninteracting system are derived in terms of the one-particle moments. For the interacting systems the third and fourth moments are derived.Keywords
