“…[209] these wave functions have been used to analyze low Q 2 data for the 16 O(e,e ′ p) reaction [198]. These very same wave functions produce a good description of the shape of the coincidence cross section for the p-shell quasihole states at high Q 2 [259] using the same spectroscopic factors obtained from the low Q 2 data [198].…”

“…An analogous result holds for transition to the p 1/2 ground state of 15 N for which the same analysis yields a spectroscopic factor Z qh 0p1/2 = 0.644. For comparison, one may note that the use of phenomenological Woods-Saxon wave functions adjusted to fit the shape of the reduced cross section require spectroscopic factors ranging from 0.61 to 0.64 for the lowest 0p 1/2 state and from 0.50 to 0.59 for the 0p 3/2 state, respectively, depending upon the choice of the optical potential for the outgoing proton [198]. Figure 42 also contains the results for the reduced cross section derived from the variational result for overlap wave function of Pieper et al [181], who employed the Argonne v 14 potential for the NN interaction [135].…”

In this picture the effects of FSI have been computed in the distorted wave impulse approximation (DWIA) [16] and the data points [198]. A spectroscopic factor of 0.537 was required for the Green's function result, while Z 0p3/2 = 0.459 has been used to for the variational calculation.…”

“…Inside this model space, the interaction used was a Brueckner G-matrix [222] derived from the Bonn-C potential [206]. For the solution of the Faddeev equations a G-matrix evaluated at a fixed starting energy ω =-25 MeV was chosen as a suitable average of the energy the most important 2h1p states that couple to the experimentally observed quasiholes [198]. However, the energy dependence of G(ω) was taken into account in the calculation of the mean field part of the self-energy, resulting in the Brueckner-HartreeFock approximation (this can be compared to the HF case in Eq.…”

Recent results obtained by applying the method of self-consistent Green's functions to nuclei and nuclear matter are reviewed. Particular attention is given to the description of experimental data obtained from the (e,e ′ p) and (e,e ′ 2N) reactions that determine one and two-nucleon removal probabilities in nuclei since the corresponding amplitudes are directly related to the imaginary parts of the single-particle and two-particle propagators. For this reason and the fact that these amplitudes can now be calculated with the inclusion of all the relevant physical processes, it is useful to explore the efficacy of the method of self-consistent Green's functions in describing these experimental data. Results for both finite nuclei and nuclear matter are discussed with particular emphasis on clarifying the role of short-range correlations in determining various experimental quantities. The important role of long-range correlations in determining the structure of lowenergy correlations is also documented. For a complete understanding of nuclear phenomena it is therefore essential to include both types of physical correlations. We demonstrate that recent experimental results for these reactions combined with the reported theoretical calculations yield a very clear understanding of the properties of all protons in the nucleus. We propose that this knowledge of the properties of constituent fermions in a correlated many-body system is a unique feature of nuclear physics.

Short-Range Correlations in Semi-exclusive Electron Scattering Experiments

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.

Short-Range Correlations and Meson Exchange Currents in Photonucleon Emission

et al. 2002

View full text Add to dashboard Cite

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)
