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