Relativistic RPA for Isobaric Analogue and Gamow-Teller Resonances in Closed Shell Nuclei
نویسنده
چکیده
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 interaction, is crucial to reproduce the latter resonances.

Comparison of the pn quasiparticle RPA and shell model for Gamow-Teller beta and double-beta decays.
We examine the validity of the pn quasiparticle RPA (pn@RPA) as a model for calculating P+ and 2vPP Gamow-Teller decays by making a comparison of the pnQRPA with a large-basis shellmodel calculation within the Of lp she11. We employ A=46 nuclei (those with six valence nucleons) for this comparison. Our comparison includes the decay matrix elements summed over final states, the strength distribu...
متن کاملSpin-isospin resonances and the neutron skin of nuclei.
The Gamow-Teller resonances (GTR) and isobaric analog states (IAS) of a sequence of even-even Sn target nuclei are calculated by using the framework of the relativistic Hartree-Bogoliubov model plus proton-neutron quasiparticle random-phase approximation. The calculation reproduces the experimental data on ground-state properties, as well as the excitation energies of the isovector excitations....
متن کاملChiral pion-nucleon dynamics in finite nuclei: spin-isospin excitations
The nuclear density functional framework, based on chiral dynamics and the symmetry breaking pattern of low-energy QCD, is extended to the description of collective nuclear excitations. Starting from the relativistic point-coupling Lagrangian introduced in Ref. [1], the proton-neutron (quasiparticle) random phase approximation is formulated and applied to investigate the role of chiral pion-nuc...

The properties of charge-exchange excitations of 208Pb with ∆L = 0, i.e., the isobaric analog and Gamow-Teller resonances, are studied within a self-consistent model making use of an effective force of the Skyrme type. The well-known isobaric analog case is used to assess the reliability of the model. The calculated properties of the Gamow-Teller resonance are compared with recent experimental ...
متن کاملRho-Nucleon Tensor Coupling and Charge-Exchange Resonances
The Gamow-Teller resonances are discussed in the context of a selfconsistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau-Migdal force by a microscopic nucleon-nucleon interaction, generated from the rho-nucleon tensor coupling. The effect of this coupling turns out to be very small when the short range correlations ...
