WebThe beta-decay strength for the weak Gamow-Teller ' transition to the ground state of 51 Cr has been measured to have log ft = 5.3893 ± 0.0016 [Aub 78]. The JP = r ground state of 51 Cr is well separated from the other excited states, and the transition from the ~ - ground state in 51 V can be measured WebGamow and Teller (1936) soon proposed a modification of Fermi’s vector theory. Fermi’s theory had originally required a selection rule, the change in \(J = 0\), where \(J\) is the angular momentum of the nucleus, and did not include the effects of nuclear spin. ...
