Nuclear Response in Electron Scattering at High Momentum Transfer

Abstract

The nuclear response functions for high energy electron scattering were calculated in the wide region of excitation energy. The three typical regions were studied: the quasi-elastic region, the $\Delta$-excitation region and the intermediate region where the meson-exchange currents give significant contribution. In the quasi-elastic and the $\Delta$ regions the response functions were found for finite size nucleus with account of relativistic kinematics. The contribution of the meson-exchange currents was calculated in the relativistic Fermi-gas model. The results were compared with the electron scattering data at high momentum transfer from ${}^{12}C$ and ${}^{16}O$.
