Abstract
We calculate cross sections and spin observables for quasielastic (pn) scattering in a relativistic plane-wave impulse approximation. Special emphasis is placed on the spin-longitudinal to spin-transverse ratio. The nuclear isovector response is calculated in nuclear matter using a relativistic random-phase approximation to the Walecka model. Inherent to the Walecka model is a dynamical reduction of the nucleon mass in the medium. The reduction of the nucleon mass is responsible for a mild softening of the longitudinal response and for no hardening of the transverse. Consequently, no large enhancement is observed in the ratio in agreement with experiment. Additional calculations are reported for incident energies in the range Tlab≅200-800 MeV.
