Quasi-Free Polarization-Transfer Measurements In The ((P)Right-Arrow, (N)Right-Arrow) Reaction At 495 Mev

Results from a complete set of polarization-transfer observables for quasifree (p -->, n -->) scattering at 495 MeV are reported. Measurements were carried out on CD2, 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-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.
