“…It has been found that the SRC slightly modifies the charge distribution in the nuclear center, confirming the results of early calculations [10,11]. However, the size of this effect is comparable to that produced by the coupling of low-lying collective phonons to the single particle wave functions [12] and therefore it is difficult to disentangle.…”

Short-Range Correlations and Meson Exchange Currents in Photonucleon Emission

One-nucleon emission processes induced by photon absorption are studied by considering shortrange correlation effects. At energies above the giant resonance region the validity of the direct knockout model has been tested by comparison with continuum random phase approximation results. Nucleon re-scattering effects have been considered by using an optical potential. The role of the electromagnetic convection, magnetization, and meson exchange currents has been investigated as a function of both excitation energy and momentum transfer. The short-range correlation effects have been studied by using various correlation functions. We found that the nucleon photo-emission cross section is rather sensitive to the presence of short-range correlations at large values of nucleon emission angle. In this region, however, the effects of meson exchange currents are even larger than those produced by short-range correlations. C 2002 Elsevier Science (USA)

“…This model has been inspired by the results of Refs. [27,28] where the density and momentum distributions of doubly closed shell nuclei, calculated with a single correlation line model, have been shown to be rather similar to those obtained with complete CBFÂFHNC calculations.…”

“…Since the cluster expansion conserves the sum rules order by order [17], the normalization of the wave function is maintained. This is immediately seen in the application of the model to the description of the ground state densities [18,19]. The validity of our model has been tested in nuclear matter by comparing our results with those obtained in a calculation that considers all the cluster terms [20].…”

“…As already pointed out in Refs. [16,18,19] the three-point diagrams reduce the effect produced by the two-point diagrams whatever it is. This is the consequence of the requirement of the conservation of the number of particles.…”

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.
