“…[6], [11], [20] and [21]). In the same line, a step further in difficulty is the SRPA [7], [24], which opens decay channels beyond one particle-one hole (1p1h) states and the Extended RPA (ERPA) ( [8], [19] and [22]), adding more complex ground state correlations than in the RPA.…”

We have performed a many-body calculation of the longitudinal nuclear (e, e ′ ) reaction employing a Second RPA (SRPA) formalism which contains the ∆(1232). More explicitly, our scheme contains RPA correlations as well as Hartree-Fock and second order self-energies, where an accurate evaluation of exchange terms is achieved. Using this formalism we have evaluated the longitudinal response function for 40 Ca. We give final results at momentum transfers ranging from 300 up to 500 MeV/c, obtaining a good agreement with data.PACS number: 21.65+f, 25.30.Fj, 21.60.Jz.

“…Jourdan,1996). From microscopic calculations (Dellafiore et al, 1985;Dieperink et al, 1976;Fabrocini and Fantoni, 1989) using realistic nuclear spectral functions we do know, however, that the response at large ω should approach zero slowly, much more slowly than the response at low ω, as a consequence of the components of large removal energy E present in realistic spectral functions S(k, E) (see e.g. Fig.…”

“…(4) at moderate momentum transfer (|q| < 0.5 GeV/c) can be carried out within nuclear many-body theory (NMBT), using nonrelativistic wave functions to describe the initial and final states and expanding the current operator in powers of |q|/m (Carlson and Schiavilla, 1998), where m is the nucleon mass. The available results for mediumheavy targets have been mostly obtained using the mean field approach, supplemented by the inclusion of model residual interactions to take into account long range correlations (Dellafiore et al, 1985).…”

This article presents a review of the field of inclusive quasi-elastic electron-nucleus scattering. It discusses the approach used to measure the data and includes a compilation of data available in numerical form. The theoretical approaches used to interpret the data are presented. A number of results obtained from the comparison between experiment and calculation are then reviewed. The analogies and differences to other fields of physics exploiting quasi-elastic scattering from composite systems are pointed out. I. INTRODUCTIONThe energy spectrum of high-energy leptons (electrons in particular) scattered from a nuclear target displays a number of features. At low energy loss (ω) peaks due to elastic scattering and inelastic excitation of discrete nuclear states appear; a measurement of the corresponding form factors as a function of momentum transfer |q| gives access to the Fourier transform of nuclear (transition) densities. At larger energy loss, a broad peak due to quasi-elastic electron-nucleon scattering appears; this peak -very wide due to nuclear Fermi motion -corresponds to processes where the electron scatters from an individual, moving nucleon, which, after interaction with other nucleons, is ejected from the target. At even larger ω peaks that correspond to excitation of the nucleon to distinct resonances are visible. At very large ω, a structureless continuum due to Deep Inelastic Scattering (DIS) on quarks bound in nucleons appears. A schematic spectrum is shown in Fig. 1. At momentum transfers above approximately 500 MeV/c the dominant feature of the spectrum is the quasi-elastic peak.A number of questions have been investigated using quasi-elastic scattering:• The quasi-elastic cross section integrated over electron energy loss is proportional to the sum of electron-nucleon cross sections. Historically, this has been exploited in order to measure the neutron charge and magnetic form factors using mainly light (A < 4) nuclear targets. Today the emphasis has shifted to exposing possible medium modifications of the nucleon form factors. * Electronic address: benhar@roma1.infn.it † Electronic address: dbd@virginia.edu ‡ Electronic address: ingo.sick@unibas.ch
