Construction and use of a mulidetector coincidence timing spectrometer system

A delayed-coincidence timing spectrometer system was constructed to measure nuclear lifetimes in the picosecond region. The present investigation used the self-comparison method of delayed-coincidence timing. This method used two plastic detectors to obtain the timing information. Two sodium iodine (NaI) detectors were used in conjunction with the plastic detectors to provide energy identification. Significant changes were made to the geometrical detector arrangement to optimize collection of scattered gamma rays by the NaI detectors. The mean line for the first excited states of the sources Co-60 and Cs-134 were measured using the new spectrometer system. The mean life of the 1.33 MeV excited state of Co-60 was measured to by 0.34 + 1.32 psec. The mean life of the 0.605 MeV excited state of Cs-134 was measured to be 6.31 + 2.19 psec and agrees with two previously reported values.Ball State UniversityMuncie, IN 47306
