Testing and characterization of a fast scintillator detector

In this paper, we report, in part, the designing and fabrication of a multi-detector system suitable for investigating the lifetime of a nucleonic state using a particle-gamma correlation setup at the University of Delhi's Nuclear Physics laboratory. Our aim is to identify the beta decay of the mother nucleus to tag that daughter nucleus, which we are interested to study for lifetime measurements. Then fast timing detectors would be used to measure the lifetime of the tagged nucleonic state. Generally we are interested to study nuclei with lifetime in the nanosecond ranges. For gamma-decay measurements, fast timing detectors such as BaF₂, LaBr₃(Ce) are used, accompanied by electronic timing methods. At our lab, we have recently procured CeBr₃ crystals and are in the process of designing a composite particle-gamma correlation detector setup. Our laboratory has the facility to populate desired nucleonic states by neutron activation technique
