    "abstract": "A phenomenological method based on the natural orbital representation is\napplied to construct the ground state one-body density matrix which describes\ncorrectly both density and momentum distributions in $^{4}He$, $^{16}O$ and\n$^{40}Ca$ nuclei. The parameters of the matrix are fixed by a best fit to the\nexperimental density distribution and to the correlated nucleon momentum\ndistribution. The method allows the natural orbitals, the occupation\nprobabilities and the depletion of the Fermi sea to be obtained. Ground-state\ncharacteristics of $^{4}He$, $^{16}O$ and $^{40}Ca$ nuclei, such as rms radii\nand mean kinetic energies are calculated, as well.",
