Dependence of nuclear binding energies on the cutoff momentum of low-momentum nucleon-nucleon interaction

Binding energies of H-3, He-4, and O-16 are calculated, using low-momentum nucleon-nucleon interactions (Vlow-k) for a wide range of the cutoff momentum A. In addition, single-particle energies in nuclei around O-16 are computed. The dependence of the binding energies and the single-particle energies in these nuclei on the cutoff momentum A of the Vlow-k is examined. Furthermore, the availability of the Vlow-k in nuclear structure calculations is discussed.
