Description

Characteristic decay properties of radionuclides are essential in the study of nuclear spectroscopy. Lifetime measurements and transition moments for excited nuclear levels form part of this extensive study that seeks to unveil properties of nuclear structure. Scintillation detectors prove to be formidable in gamma ray detection and lifetime measurements. With advent of LaBr3 detectors it is now possible to have both excellent timing properties, (around 300ps) and energy resolution (approximately 3.0% at 1332keV ). Recently a fast timing array has been commissioned at iThemba LABS, Cape Town consisting of eight 2” by 2” LaBr3(Ce) detectors. Several experiments been performed with short-lived radioactive sources showing impressive lifetime measurements. Furthermore, the detectors were used for in-beam measurements at iThemba LABS in order measure the nuclear lifetimes of 42Ca, 44Sc and 62,63Ni. Results will be presented of the measurements undertaken for radioactive sources.
