Abstract
It is shown that the effects of antisymmetrization between the quarks in different nucleons in the nucleus can be very strong. Using a schematic model in which a nucleus consists of two identical nucleons with two quarks each, the effects of antisymmetry on the charge form factor, quasielastic response function, Coulomb sum rule, and quark momentum distributions in nuclei are studied. In particular, it is found that the antisymmetrization leads to a violation of three commonly used prescriptions: factorization of the nucleon form factor, scaling in quasielastic electron scattering, and separation of nuclear and nucleon effects in Fermi smearing in deep-inelastic electron scattering.
