Description

The isospin-forbidden neutron decay of the isobaric analog state in 208Bi has been measured, following its excitation via the 208Pb(3He,t)208Bi reaction at 61.2 MeV. In contrast to the proton decay, which is direct, the neutron decay spectrum has a statistical shape. Its branching ratio is determined to be (37 ± 3)%. The results suggest that the damping of the isospin impurity is fast. Therefore, neutron decay results mostly from the final stage of the damping process and does not contribute to the width of the IAS. ((orig.))
