Query: Realistic Effective Interactions and Large-Scale Nuclear Structure
  Calculation   We describe the properties of complex nuclei, such as the Sn isotopes with
mass numbers A = 100 - 132, in terms of the free nucleon--nucleon interaction
as obtained from meson--exchange theory. This amounts to first calculating an
effective interaction in which the free interaction is modified by the presence
of the appropriate nuclear medium. The short--range correlations are included
within the framework of Brueckner theory yielding the nuclear reaction matrix
and the long--range correlations by using the reaction matrix in many--body
perturbation theory to obtain an effective interaction. The resulting effective
interaction is then employed in calculating the nuclear properties. Particular
emphasis is placed on the ability of our calculation to describe systematic
trends of the properties of these nuclei. Both successful achievements and
problematic features are pointed out.
