Finite nuclei calculations with realistic potential models

An effective interaction is deduced from a microscopic point of view for different realistic N-N interactions. The effect of second order and folded diagrams is considered in the calculation of the low-energy spectra of some light s-d shell isotopes. We confirm that the Bonn-A potential gives the best agreement with data. The Paris and Argonne υ14 potentials display a very similar behaviour. The general trend of the results shows better agreement with data for potentials with weaker tensor force components, but other details of the construction of the potentials might contribute to this effect.
