Abstract :
The performance of new scintillator detectors based on LaBr3(Ce) technology was evaluated in conjunction with the Gammasphere spectrometer. Specifically, the lifetimes of states between 50 ps and 1 ns, populated in the decay of the 177mLu isomeric state (T1/2=160 d), have been measured. Even though the decay scheme is rather complex, it is possible to perform precise measurements because of the superior energy resolution of the LaBr3(Ce) detectors, compared to that of BaF2 scintillators, when used in combination with the power of the Gammasphere array to isolate a specific γ cascade.
