Abstract:
The decay of the neutron-rich isotope Bi-216, produced by proton-induced spallation at the PS Booster-ISOLDE facility, was investigated by beta - gamma gamma, alpha gamma coincidence and spect;rum-multiscaling measurements. A new method for reducing isobaric contamination enabled to cover the unknown region "east" of Pb-208 for, the isobaric chain A=216. The half-life of the beta decay of Bi-216 was found as T-1/2 = 135 +/- 5 s. Its decay scheme was extended and the possible shell model configurations are proposed.
