| Abstract | The pairing properties of nuclear systems are a sensitive probe of the effective nucleon-nucleon interactions. We compare the 1 S0 pairing gaps in nuclear and neutron matter derived from the phenomenological Gogny interaction and a renormalization group motivated low-momentum Vlow k interaction extracted from realistic interactions. We find that the pairing gaps predicted by these interactions are in an excellent agreement in a wide range of sub-nuclear densities. The close agreement between the predictions of the effective forces remains intact in the case where the single particle spectra in neutron and nuclear matter are renormalized within the Hartree-Fock theory. The effective nuclear forces are the key ingredients in the nuclear structure studies of finite nuclei within the Hartree-Fock-Bogoliubov and related mean field theories. Well-known examples are the zero-range Skyrme [1] and finiterange Gogny [2,3] forces that have extensively been used in the large scale numerical calculations of finite nuclei over several decades.
