Abstract
Separable nucleon-nucleon potentials are calculated using inverse scattering techniques as presented in previously published work. The dependence of the potentials on the momentum cut-off of the scattering phase-shifts is studied. Some comparison is made with the V-low-k potential. The effect of the cut-off on nuclear matter binding energy calculated by standard Brueckner theory is also presented. It is foumd that a cut-off larger than about 4 fm-1 will keep the error to within one Mev around saturation density. While the potentials are cut-off dependent the effective interaction represented by the Brueckner K-matrix is less sensitive to this cut-off. This is in particular found to be the case for the 1S0 state.
