0 Shell model study of the isobaric chains
Shell model calculations in the full pf -shell are carried out for the A=50, 51 and 52 isobars. The most frequently used effective interactions for the pf -shell, KB3 and FPD6 are revisited and their behaviour at the N=28 and Z=28 closures examined. Cures to their -relatively minordefaults are proposed, and a new mass dependent version called KB3G is released. Energy spectra, electromagnetic tr...
متن کاملMixed-Mode Shell-Model Calculations
A one-dimensional harmonic oscillator in a box is used to introduce the oblique-basis concept. The method is extended to the nuclear shell model by combining traditional spherical states, which yield a diagonal representation of the usual single-particle interaction, with collective configurations that track deformation. An application to 24Mg, using the realistic two-body interaction of Wilden...
متن کاملMixed-Symmetry Shell-Model Calculations
The one-dimensional harmonic oscillator in a box problem is used to introduce the concept of an oblique-basis shell-model theory. The method is applied to nuclei by combining traditional spherical shell-model states with SU(3) collective configurations. An application to Mg, using the realistic two-body interaction of Wildenthal, is used to explore the validity of this oblique-basis, mixed-symm...
متن کاملShell - model calculations of neutrino scattering from 12 C
Neutrino reaction cross-sections, (ν µ , µ −), (ν e , e −), µ-capture and photoab-sorption rates on 12 C are computed within a large-basis shell-model framework , which included excitations up to 4¯ hω. When ground-state correlations are included with an open p-shell the predictions of the calculations are in reasonable agreement with most of the experimental results for these reactions. Woods-...
متن کاملRelativistic RPA for Isobaric Analogue and Gamow-Teller Resonances in Closed Shell Nuclei
We perform a selfconsistent relativistic RPA calculation for the isobaric analogue and Gamow-Teller resonances based on relativistic mean field theory results for the ground states of Ca, Zr and Pb. We use the parameter set NL1 for the σ, ω and ρ mesons, and experimental values for the pion and nucleon. An extra parameter, related to the intensity of the contact term in the pion-exchange intera...
