Change of Scale for Nucleons in Nuclei from Quasielastic Electron Scattering

Quasielastic electron scattering ($0.1\lesssim Q^2\lesssim 1$ Ge${\mathrm{V}}^2$) may be well suited to measure modifications of nucleons in nuclei. From an analysis of the longitudinal and transverse structure functions for inelastic electron scattering off ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ in the region $0.1\lesssim Q^2\lesssim 0.25$ Ge${\mathrm{V}}^2$, indications are found for increases of the charge radius and the magnetic moment of nucleons in ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$. The mean square radius of the magnetic form factor shows virtually no increase.
