LIBRARIES Kinematic Scaling in Quasielastic Electron Scattering

The kinematic scaling behavior of quasielastic scattering is investigated using existing inclusive scattering data on 12C, w a, 4 8 ~ a, S 6 ~ e, and *08pb from the Centre d'~tudes Nuclbaires de Saclay, and &ca from the Bates Linear Accelerator Center. The cross sections are re-analyzed using the effective momentum approximation to correct for Coulomb distortion effects. Rosenbluth separations are performed for momentum transfers from 300 to 550 MeV/c. The scaling of the separated longitudinal and transverse response functions is studied for three scaling variables: y; a model-independent variable derived from the plane wave impulse approximation, Y; derived from the relativistic Fenni gas model, and Y'; a variation on Y that incorporates a realistic separation energy. The Saclay data exhibit a longitudinal-transverse scale breaking; the longitudinal and transverse responses do not scale to the same function. The Bates longitudinal and transverse responses for w a do scale to the same function in accordance with theory. The discrepancy between the Bates and Saclay data for %a is examined in detail. The integrated longitudinal response functions are compared to Fermi gas predictions for al
