Y-SCALING QUANTITIES AND NUCLEON CORRELATION EFFECTS IN NUCLEI

Abstract

The asymptotic scaling function F(y) and the binding correction B(y), the mean kinetic 〈T〉 and removal 〈E〉 energies, as well as the occupation probabilities Sgr and Sex are calculated in the cases of the 4He, 12C, 16O and 40Ca nuclei using the nucleon momentum distributions obtained within the Jastrow correlation method and the phenomenological model which takes into account short-range and tensor nucleon-nucleon correlations. It is shown that the scaling functions F(y) differ from those obtained in the mean-field approximation but qualitatively agree with the available experimental data. The binding correction B(y) is explicitly evaluated using a model nuclear spectral function. The nucleon-nucleon correlation effects increase the values of the mean kinetic 〈T〉 and mean removal 〈E〉 energies in comparison with their values in the mean-field approximation.
