Central Jastrow and linear state-dependent correlations in nuclei

Linearized state-dependent and central Jastrow correlated trial wavefunctio ns are used to study the ground state of spin-isospin saturated p-shell nuc lei with V4-type forces. We extend the variational Monte Carlo method to in corporate this kind of operatorial correlation by introducing only minor ch anges with respect to the case of central correlations. Very good energies are obtained with this wavefunction for the nuclei studied. Finally, a disc ussion of the role of the different correlation mechanisms included in this trial wavefunction is performed in terms of both the momentum distribution and the one- and two-particle densities in position space.
