Query: Nuclear response functions in homogeneous matter with finite range
  effective interactions   The question of nuclear response functions in a homogeneous medium is
examined. A general method for calculating response functions in the random
phase approximation (RPA) with exchange is presented. The method is applicable
for finite-range nuclear interactions. Examples are shown in the case of
symmetric nuclear matter described by a Gogny interaction. It is found that the
convergence of the results with respect to the multipole truncation is quite
fast. Various approximation schemes such as the Landau approximation, or the
Landau approximation for the exchange terms only, are discussed in comparison
with the exact results.
