Shell-model calculations and realistic effective interactions
A review is presented of the development and current status of nuclear shell-model calculations in which the two-body effective interaction between the valence nucleons is derived from the free nucleon-nucleon potential. The significant progress made in this field within the last decade is emphasized, in particular as regards the so-called Vlow−k approach to the renormalization of the bare nucl...
متن کاملShell-Model Calculations with Realistic Effective Interactions
In this paper, we present some results of shell-model calculations employing effective interactions derived from the CD-Bonn free nucleon-nucleon potential. These concern 18O, 134Te, and 210Po, and are part of a comprehensive study of nuclei around doubly closed shells. Comparison of the calculated results with experimental data illustrates the degree of accuracy of modern realistic shell-model...
متن کاملPseudo-SU(4) Model and Beta Decay of pf-shell Nuclei
The pf-shell (i.e. the 2p 1 2 -2p 3 2 -1f 5 2 shell) is important for a variety of problems in nuclear structure, however, the study of this shell has been hindered by the huge size of the shell model space. In recent years there have been studies by using the Monte-Carlo shell model [1] and that based on the pseudo-SU(4) symmetry model [2]. The original Wigner Supermultiplet SU(4) model[3] is ...
متن کاملShell-model analysis of the 136Xe double beta decay nuclear matrix elements.
Neutrinoless double beta decay, if observed, could distinguish whether the neutrino is a Dirac or a Majorana particle, and it could be used to determine the absolute scale of the neutrino masses. 136Xe is one of the most promising candidates for observing this rare event. However, until recently there were no positive results for the allowed and less rare two-neutrino double beta decay mode. Th...
متن کاملShell-model calculation for two-neutrino double beta decay of 48Ca.
The 2vPP decay matrix element of 'Ca has been studied in a large basis shell-model space. The theoretical and experimental p and p+ spectra and their relation to 2vpp are discussed. A new empirical effective interaction is found to give the best agreement to p and p+ spectra with the effective Gamow-Teller operator 0 t =0.770t. The predicted Tl ~2 =1.9X 10' yr differs by a factor of 2 from the ...
