Results from a complete set of polarization-transfer observables for quasifree ([rvec p], [rvec n]) scattering at 495 MeV are reported. Measurements were carried out on CD[sub 2], carbon, and calcium targets at a laboratory scattering angle of 18[degrees] using the new Neutron Time-of-Flight facility at LAMPF. The ratio of spin-longitudinal to spin-transverse responses at a momentum transfer of approximately 1.72 fm[sup [minus]1] is extracted from the data, as well as the separated responses, and compared to distorted-wave calculations incorporating a Random-Phase Approximation description of the nuclear response. Thespin-transverse response is compared to (e,e[prime]) measurements. The spin-longitudinal response represents new information available from hadron scattering.
