Quark exchange and nuclear form factors

The Pauli principle requires nuclear wavefunctions to be antisymmetrized on the quark level. For a properly antisymmetrized wavefunction compared with a conventional nuclear wavefunction this means the introduction of quark-exchange terms. We included dinucleonic quark-exchange terms in the wavefunctions of p-shell nuclei and calculated observables. In the charge form factor the quark exchanges dominate for high momentum transfer. For heavier nuclei the importance of the quark-exchange contributions decreases.
