“…We have studied electron induced two-nucleon emission processes by applying a model which has been already used to describe inclusive [1,10] and one nucleon emission processes [2,3]. In this model, inspired to the correlated basis function theory, the full cluster expansion is truncated to consider all, and only, those diagrams containing a single correlation function h(r).…”

“…We found that the SRC produce small effects and are unable to account for the quenching required to reproduce the data. Electron scattering inclusive reactions in the quasi-elastic region have been investigated in [1]. In this case the effect of the correlations is much smaller than that produced by the final state interaction, and therefore difficult to disentangle.…”

A model to study two-proton emission processes induced by electron scattering is developed. The process is induced by one-body electromagnetic operators acting together with short-range correlations, and by two-body ∆ currents. The model includes all the diagrams containing a single correlation function. A test of the sensitivity of the model to the various theoretical inputs is done. An investigation of the relevance of the ∆ currents is done by changing the final state angular momentum, excitation energy and momentum transfer. The sensitivity of the cross section to the details of the correlation function is studied by using realistic and schematic correlations. Results for 12 C, 16 O and 40 Ca nuclei are presented.

Antisymmetrized Green’s function approach to (e,e′) reactions with a realistic nuclear density

A completely antisymmetrized Green's function approach to the inclusive quasielastic (e, e ′ ) scattering, including a realistic one-body density, is presented. The single particle Green's function is expanded in terms of the eigenfunctions of the nonhermitian optical potential. This allows one to treat final state interactions consistently in the inclusive and in the exclusive reactions. Nuclear correlations are included in the one-body density. Numerical results for the response functions of 16 O and 40 Ca are presented and discussed.

One-nucleon emission electron scattering experiments are studied with a model that considers short-range correlations up to the first order in the number of correlation lines. The proper normalization of the many-body wave functions requires the evaluation of two-and three-point diagrams, the last ones usually neglected in the literature. When all these diagrams are included the effects of the short-range correlations are rather small. The results of our calculations are compared with experimental data taken on 16 O.
