Missing and quenched Gamow-Teller strength.
Gamow-Teller strength functions in full (pf) spaces are calculated with sufficient accuracy to ensure that all the states in the resonance region have been populated. Many of the resulting peaks are weak enough to become unobservable. The quenching factor necessary to bring into agreement the low lying observed states with shell model predictions is shown to be due to nuclear correlations. To w...

متن کاملA / I ? + Gamow - Teller strength in nuclei
The distribution of p+ Gamow-Teller strength in 26Mg, 54Fe and 56Ni is calculated in the QRPA and large-basis shell-model spaces. The quenching relative to the simplest jj coupled model found in the QRPA is similar to that found in a shell-model basis which includes 2p2h ground-state correlations within the major shell (sd or pf). For 26Mg there is significant additional quenching found in the ...
متن کاملGamow-teller Sum Rule in Relativistic Nuclear Models
Relativistic corrections are investigated to the Gamow-Teller(GT) sum rule with respect to the difference between the β− and β+ transition strengths in nuclei. Since the sum rule requires the complete set of the nuclear states, the relativistic corrections come from the anti-nucleon degrees of freedom. In the relativistic mean field approximation, the total GT strengths carried by the nucleon s...
