Ground state correlations in 16O and 40Ca
Abstract
We study the ground state properties of doubly closed shell nuclei 16O and 40Ca in the framework of correlated basis function theory using state dependent correlations, with central and tensor components. The realistic Argonne v14 and v'8 two-nucleon potentials and three-nucleon potentials of the Urbana class have been adopted. By means of the Fermi hypernetted chain integral equations, in conjunction with the single operator chain approximation, we evaluate the ground state energy, one- and two-body densities and electromagnetic and spin static responses for both nuclei. In 16O we compare our results with the available Monte Carlo and coupled cluster ones and find a satisfying agreement. As in the nuclear matter case with similar interactions and wave functions, the nuclei result underbound by 2-3 MeV/nucleon.
