AbstractAbstract

[en] One body density matrix elements (OBDME) for select transitions in

^{12}C have been calculated in a complete space, for positive parity final states, and a restricted shell model space for negative parity final states. These OBDMEs are given in a form that is suitable for use in analyses of elastic and inelastic scattering data. It is found that corrections such as core polarisation are naturally included in these large space shell model calculations. 17 refs., 24 tabsPrimary Subject

AbstractAbstract

[en] Effective two nucleon (NN) interactions in the nuclear medium have been defined from an accurate mapping of NN g matrices obtained by solving the Brueckner-Bethe-Goldstone (BBG) equations for infinite nuclear matter. Those effective interactions have been used in fully microscopic calculations of (nonlocal) effective proton-light nuclei interactions with which we have obtained predictions of the differential cross sections and analysing powers from elastic scattering. Results for incident proton energies of 65 and 200 MeV are considered in particular herein. The relative motion wave functions so found then have been used as the distorted waves in distorted wave approximation (DWA) studies of select inelastic scattering events. The same effective interactions were used as the transition operators in those calculations. The relevant nuclear spectroscopy for the elastic and DWA (p, p') calculations has been found from full (0+2)ℎω shell model evaluations of the nuclear structure; wave functions of which give good descriptions for many measured longitudinal, transverse electric and transverse magnetic form factors from electron scattering. 12 refs., 17 figs

AbstractAbstract

[en] Comparison is made between calculations of transverse electric form factors using the standard expression for the electric multipole operator with those obtained by invoking current conservation first in the long wavelength limit and second for arbitrary momentum transfer. Results are presented for select E2 transitions in

^{12}C,^{20}Ne,^{24}Mg, and^{28}Si. It is found that the form factors differ significantly when the conventional shell model wave functions are used, confirming that these do violate current conservation. However, the variation between results is much smaller when multi-shell models of nuclear structure are used. All three forms of the operator yield comparable good agreement with existing data indicating that wave functions obtained from these models are largely current conserving. 19 refs., 5 tabs., 7 figsPrimary Subject

AbstractAbstract

[en] The astrophysical S factor for the

^{7}Be(p, γ)^{8}B reaction at threshold is investigated using simple models to determine the model dependence in the extrapolation of the laboratory data to the region of astrophysical interest near 20 keV. We find that the energy dependence below 400 keV is largely well understood in terms of the Coulomb interaction and constrained by the data for the elastic scattering of low-energy neutrons from^{7}LiPrimary Subject

AbstractAbstract

[en] Elastic and inelastic scattering data from the scattering of 160 MeV protons from

^{14}N, and of 200 MeV protons from^{16}O have been analysed using a fully microscopic Distorted Wave Approximation. The analyses involve large space (multi-ℎ ω) shell model wave functions, an effective nucleon-nucleon interaction that is energy and medium dependent, and fully microscopic (nonlocal) optical potentials built with that same effective interaction. The results for^{14}N and^{16}O correlate with analyses of elastic and inelastic electron scattering form factors indicating that improvements are needed in the shell model interactions used to obtain the nuclear wave functions. 28 refs., 2 tabs., 8 figsPrimary Subject

AbstractAbstract

[en] An effective two nucleon (NN) interaction in the nuclear medium is defined from an accurate mapping of the NN g matrices obtained by solving the Brueckner-Bethe-Goldstone equations for infinite nuclear matter. That effective interaction is used in a fully microscopic calculation of the nonlocal effective proton-

^{12}C interaction from which are obtained predictions of the differential cross section and analysing power for 200 MeV elastic scattering. The relative motion wave functions so found are used as the distorted waves in a distorted wave approximation (DWA) study of select inelastic scattering events. The effective NN interaction is used as the transition operator in those calculations. The relevant nuclear spectroscopy for the elastic and DWA (p, p') calculations is found from a full (0 + 2) ℎω shell model evaluation of the positive parity states while a restricted (1 + 3)ℎω has been used to give the negative parity states. Results are compared with those of the 0p-shell model of Cohen and Kurath or with those based upon axially symmetric, projected Hartree-Fock calculations. The diverse structure model wave functions are assessed by using them in calculations to compare with measured longitudinal, transverse electric and transverse magnetic form factors from electron scattering to many of the excited states of^{12}C. Using those models of the structure of^{12}C in the completely microscopic model of the elastic and inelastic scattering of 200 MeV protons, good fits have been found to the cross section and analysing power data. 50 refs., 3 tabs., 20 figsPrimary Subject

AbstractAbstract

[en] A fully microscopic calculation of inelastic proton scattering off

^{208}Pb is presented, and compared to experimental scattering data for incident proton energies between 65 and 201 MeV. By constructing the nucleon-nucleus interaction through the folding of nuclear structure information with a reliable nucleon-nucleon effective interaction that has no adjusted parameter, a consistent framework is built, for probing the influence of different descriptions of nuclear structure on nucleon inelastic scattering predictions. The absence of phenomenological normalization in this framework guarantees a unique and unambiguous interpretation of our calculations in terms of quality of the underlying nuclear structure description: a feature that had been reserved, until recently, to the electron probe. This tool is used to investigate the effect of long range correlations embedded in excited states, on calculated inelastic observables, demonstrating the sensitivity of nucleon scattering predictions to details of the nuclear structurePrimary Subject

AbstractAbstract

[en] Analyses of intermediate energy nucleon-nucleus scattering made using nonlocal optical potentials obtained by full folding medium modified effective NN interactions are sensitive to the target nucleon densities used. As the effective interaction and the structure details are all preset and no a posteriori adjustment or simplifying approximation is made to the (g-folded) optical potentials, the observables obtained are predictions and they match data well. The procedure, under inverse kinematics, also explains radio-active ion beam data from scattering of exotic, halo nuclei, from Hydrogen
