Abstract: A method calculating one body density matrix of nucleus in the mean field shell model is proposed.One body density matrixes of double closed nuclei 40Ca,90Zr are calculated. The nucleon density and momentum distributions are calculated and compared with those by the Hatree-Fock-Bogolubov theory,local Fermi gas model and those by experiments,respectively.

Key words: one body density matrix, shell model, density distribution
