Gamow-Teller β transition from the 2- ground state of88Rb to the 3- excited state of88Sr
The Gamow-Teller β-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 lof ft value are calculated using complete nuclear wave functions for the initial and final states. It is shown that, contrary to the normal assumption...
