    "abstract": "We study microscopically the ground state properties of 16O and 40Ca nuclei\nwithin correlated basis function theory. A truncated version of the realistic\nUrbana v14 (U14) potential, without momentum dependent terms, is adopted with\nstate dependent correlations having spin, isospin and tensor components. Fermi\nhypernetted chain integral equations and single operator chain approximation\nare used to evaluate one- and two-body densities and ground state energy. The\nresults are in good agreement with the available variational MonteCarlo data,\nproviding a first substantial check for the accuracy of the cluster expansion\nmethod with state dependent correlations. The finite nuclei treatment of non\ncentral interactions and correlations has, at least, the same level of accuracy\nas in infinite nuclear matter. The binding energy for the full U14+TNI\ninteraction is computed, addressing its small momentum dependent contributions\nin local density approximation. The nuclei are underbound by about 1 MeV per\nnucleon. Further energy lowering might be achieved by a more accurate\nvariational minimization.",
