Description

We reexamine the role of two particle-two hole (2p2h) ground state correlations (GSC) on electron scattering in the quasielastic region. An extended RPA including explicitly the interaction of 1p1h excitations with both 2p2h and 3p3h excitations in the final state is presented. Formulas for the longitudinal and transverse structure functions are given in the framework of the Fermi gas model of the nucleus. As an example, numerical results for the spin-isospin response in 56Fe are shown. We conclude that the effect of the GSC on the static structure functions is negligible. (orig.)
