Results from a complete set of polarization-transfer observables for quasifree ({ital {rvec p}},{ital {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{degree} 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 and compared to distorted-wave calculations incorporating a random-phase approximation description of the nuclear response. No enhancement is observed in the experimental ratio.
