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.
