  A linked cluster expansion for the calculation of ground state observables of
nuclei with realistic interactions has been developed. Using the V8' potential
the ground state energy, density and momentum distribution of complex nuclei
have been calculated and found to be in good agreement with the results
obtained within the Fermi Hyper Netted Chain, and Variational Monte Carlo
approaches. Using the same cluster expansion, with wave function and
correlations parameters fixed from the calculation of the ground-state
observables, various high energy scattering processes off complex nuclei have
been calculated taking final state interaction effects into account by means of
the Glauber multiple scattering series.
