Abstract: (APS)

A relativistic finite nucleus calculation using a Dirac optical potential is used to investigate the importance of final state interactions (FSI) at large momentum transfers in inclusive quasielastic electronuclear reactions. The optical potential is derived from first-order multiple scattering theory and then is used to calculate the FSI in a nonspectral Green’s function doorway approach. At intermediate momentum transfers excellent predictions of the quasielastic Fe56(e,e’) experimental data for the longitudinal response function are obtained. In comparisons with recent measurements at ‖q→‖=1.14 GeV/c the theoretical calculations of RL give good agreement for the quasielastic peak shape and amplitude, but place the position of the peak at an energy transfer of about 40 MeV higher than the data.
