Philosophiae Doctor - PhD / The progressive development of scintillator detectors has made it possible to perform direct electronic
lifetime determination up to a few hundred nanoseconds. The 2" by 2" LaBr3:Ce detectors
provide a combination of excellent time resolution and good energy resolution. Recently a fast
timing array has been commissioned at iThemba LABS, Cape Town consisting of eight 2" by 2"
LaBr3:Ce detectors. Test measurements using radioactive sources produced at the laboratory were
conducted. Six 2" by 2" LaBr3:Ce detectors were coupled to the AFRODITE array as their rst
in-beam experiment. AFRODITE consisted of eight HPGe clover detectors as well as two 3.5" x
8" LaBr3:Ce detectors. A particle telescope was used to select the desired reaction channels. The
reactions of interest 45Sc(p,d)44Sc and 45Sc(p, )42Ca were carried out at a beam energy of 27 MeV.
The current analysis also investigates the rare earth nucleus 150Gd which was populated through
150Sm( ,4n)150Gd at a beam energy of 48 MeV.
