Short range correlations and fractional occupation probabilities.

Abstract

The results of a recent study about the role of short-range correlations on the occupation numbers of the shell model orbits in light nuclei are reconsidered by assuming a sort of state dependence of the single particle wave functions in the ``natural orbital'' representation, which is used for the determination of the occupation probabilities. It turns out that such a treatment leads to a significant reduction of the total depletion of the nuclear Fermi sea. The state dependence of short-range correlations is also discussed.
