Abstract. Analytical expressions for the one-body density matrix and the related characteristics of closed s-d shell nuclei are obtained within the low-order approximation to the Jastrow correlation method. The correlation effects on the nucleon momentum and density distributions as well as the occupation numbers and the depletion of the Fermi sea are discussed. It is pointed out that the use of the low-order approximation leads to a violation of the A-representability condition for the one-body density matrix.
