  The Landau parameters obtained from the matrix elements of an effective
interaction recently derived within the formalism of correlated basis functions
have been used to carry out a study of the weak response of neutron matter in
the region of low momentum transfer. The proposed approach allows for a
consistent description of different interaction effects and can be extended to
describe matter at non vanishing temperature. The results show that
interactions lead to a sizable enhancement of the neutrino mean free path in
cold neutron matter. The dependence of the mean free path on temperature and
neutrino energy is also analyzed.
