Abstract
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.
