  The effects of the spin-orbit component of the particle-hole interaction on
nuclear response functions and neutrino mean free path are examined. A complete
treatment of the full Skyrme interaction in the case of symmetric nuclear
matter and pure neutron matter is given. Numerical results for neutron matter
are discussed. It is shown that the effects of the spin-orbit interaction
remain small, even at momentum transfer larger than the Fermi momentum. The
neutrino mean free paths are marginally affected.
