Abstract

An effective two nucleon ({ital NN}) interaction in the nuclear medium is defined from an accurate mapping of the {ital NN} {ital 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-{sup 12}C interaction from which we obtain predictions of the differential cross section and analyzing 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 {ital NN} interaction is used as the transition operator in those calculations. The relevant nuclear spectroscopy for the elastic and DWA ({ital p},{ital p}{prime}) calculations is found from a full (0+2){h_bar}{omega} shell model evaluation of the positive parity states while a restricted shell model space (1+3){h_bar}{omega} has been used to give the negative parity states. Results are compared with those of the 0{ital p}-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 factorsmore »« less

Fully microscopic model analysis of the elastic and inelastic scattering of protons from {sup 12}C and for energies in the range 200 to 800 MeV

Journal Article Dortmans, P; Karataglidis, S; Amos, K; ... - Physical Review, C

Medium modified effective two nucleon interactions are defined for protons incident upon {sup 12}C with energies in the range 200 to 800 MeV. Those effective interactions have been folded with the ground-state density to specify nonlocal optical potentials that were then used to analyze the elastic scattering differential cross sections and analyzing powers. A select set of isoscalar and isovector, positive and negative parity, inelastic proton scattering transitions have also been analyzed using the same (microscopic) optical models to define the distorted wave functions needed in distorted wave approximation (DWA) calculations of the associated differential cross sections and analyzing powers.more »« less

Scattering of polarized protons from sup 6 Li at 200 MeV

Journal Article Glover, C; Foster, C; Schwandt, P; ... - Physical Review, C (Nuclear Physics); (USA)

New cross section and analyzing power data are presented for elastic and inelastic scattering of 200 MeV protons from {sup 6}Li. The elastic data are well described by a standard, spherical, 12-parameter phenomenological Woods-Saxon (WS) optical potential. Microscopic folding-model optical potentials, obtained by convoluting free and Pauli-corrected effective nucleon-nucleon ({ital NN}) interactions with {sup 6}Li ground-state densities constrained by electromagnetic data, produce satisfactory descriptions of the elastic data. The effects of the spin-spin optical potential, estimated via the distorted wave approximation (DWA), are small but not negligible.

Electron scattering from {sup 10}B

Journal Article Cichocki, A; Dubach, J; Hicks, R; ... - Physical Review, C

Electron scattering measurements have been made in order to determine the longitudinal and transverse form factors of low-lying level in {sup 10}B. With the exception of the broad 5.18 MeV level, results were obtained for all known levels up to 6.7 MeV. The measurements span the momentum transfer range. The primary objective of this work was to improve the data on the pure isovector {ital M}3 form factor of the 1.740 MeV excitation, the transform of which yields the 1{ital p}{sub 3/2} single-nucleon wave function. A Woods-Saxon potential was found to provide a much better representation of the data thanmore »« less

Scattering of polarized protons from sup 7 Li at 200 MeV

Journal Article Glover, C; Foster, C; Schwandt, P; ... - Physical Review, C (Nuclear Physics); (USA)

New cross-section and analyzing-power data are presented for elastic and inelastic scattering of 200-MeV protons from {sup 7}Li, which has a 3/2{sup {minus}}, {ital T}=1/2 ground state. A microscopic folding-model optical potential, obtained by convoluting a Pauli-corrected effective nucleon-nucleon ({ital NN}) interaction with {sup 7}Li ground-state densities constrained by weak and electromagnetic data, produces a satisfactory description of the elastic data. The effects of the nonspherical terms in the optical potential, estimated via the distorted-wave approximation (DWA), are appreciable. The inelastic transitions leading to the 1/2{sup {minus}},{ital T}=1/2 and 7/2{sup {minus}},{ital T}=1/2 states at 0.48 and 4.63 MeV, respectively, aremore »« less

Multi-{h_bar}{omega} shell model analyses of elastic and inelastic proton scattering from {sup 14}N and {sup 16}O

Journal Article Karataglidis, S; Dortmans, P; Amos, K; ... - Physical Review, C

Elastic and inelastic scattering data from the scattering of 160 MeV protons from {sup 14}N, and of 200 MeV protons from {sup 16}O have been analyzed using a fully microscopic distorted wave approximation. The analyses involve large space (multi-{h_bar}{omega}) 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 {sup 14}N and {sup 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 wavemore »« less
