The polarization correction to the single particle energies have been calculated using a self consistent HFB theory. It is shown that this corrections are predominantly due to the particle to vibration coupling. To do so, the vibrations have been treated in a fully self-consistent QRPA approach, and we keep the full interaction in the PVC vertex. The importance of the self-interaction term in the case of density dependent interaction is discussed briefly. Results for the fit of the density dependent interaction on some experimental data sets will be discussed.
