Inclusive electron scattering from nuclei in the quasielastic region at large momentum transfer
- California Inst. of Technology (CalTech), Pasadena, CA (United States)
Experiment E02-019, performed in Hall C at the Thomas Jefferson National Accelerator Facility (TJNAF), was a measurement of inclusive electron cross sections for several nuclei (2H,3He, 4He, 9Be,12C, 63Cu, and 197Au) in the quasielastic region at high momentum transfer. In the region of low energy transfer, the cross sections were analyzed in terms of the reduced response, F(y), by examining its y-scaling behavior. The data were also examined in terms of the nuclear structure function νWA 2 and its behavior in x and the Nachtmann variable ξ. The data show approximate scaling of νWA 2 in ξ for all targets at all kinematics, unlike scaling in x, which is confined to the DIS regime. However, y-scaling observations are limited to the kinematic region dominated by the quasielastic response (y <0), where some scaling violations arising from FSIs are observed.
