Gamow-Teller β transition from the 2− ground state of88Rb to the 3− excited state of88Sr
The Gamow-Tellerβ-transition from the ground state 2− of88Rb to the 3− level at 2.734 MeV of88Sr is studied. The nuclear matrix element σ〉and the lofft value are calculated using complete nuclear wave functions for the initial and final states. It is shown that, contrary to the normal assumption, th...

| Sumario: | The Gamow-Tellerβ-transition from the ground state 2− of88Rb to the 3− level at 2.734 MeV of88Sr is studied. The nuclear matrix element σ〉and the lofft value are calculated using complete nuclear wave functions for the initial and final states. It is shown that, contrary to the normal assumption, the component ¦π2p 3 2/−1 π1g9/2〉 of the final state does give a very important contribution to〈σ〉due to the presence of strong cancellation effects. Although our calculations favour a wave function for the 3− level88Sr where neutron 1h—1p configurations are not included, there are still some facts which make that our results cannot be taken as conclusive. |
