Quasifree ({rvec p}, {rvec n}) reactions and enhancement of pionic processes
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.
