Dependence of Nuclear Binding Energies on the Cutoff Momentum of Low-momentum Nucleon-nucleon Interaction

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