Particle emission from different shells after electroexcitation of a nucleus is studied in the quasielastic region of the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$(e,e’p${)}^{11}$B reaction. The rescattering processes and in particular the coupling between (e,e’p) and (e,e’n) channels show a sizable density dependence. The resulting shell dependence of the longitudinal/transverse suppression, using the free nucleon form factors, is close to the one observed in the experimental data.
