  The structure of finite nuclei is investigated by employing an interaction
model which is based on the low-momentum interaction $V_{lowk}$. It is
supplemented by a density-dependent contact interaction fitted to reproduce the
saturation properties of infinite nuclear matter within the Hartree-Fock
approach. The calculations of finite nuclei are performed in a basis of plane
waves discretized in a cartesian box of appropriate size. As a first example
the structure of Ne isotopes is considered ranging from $^{18}$Ne to the
neutron drip line. Rather good agreement is obtained for the bulk properties of
these nuclei without any free parameter. The basis is also appropriate to
describe other deformed nuclei and the transition from discrete nuclei to
homogeneous matter which is supposed to occur in the crust of neutron stars.
