DESCRIPTION:Speakers: Lumkile Msebi (UWC\, iThemba LABS)\nThe progressive 
 development of the scintillator detectors has made it possible to do direc
 t electronic lifetime determination. The 2” x 2” LaBr3:Ce detectors pr
 ovide a combination of excellent time resolution and good energy resolutio
 n. With these detectors it is possible to perform direct lifetime measurem
 ents of excited nuclear states up to  a few hundred picoseconds. Six 2” 
 x 2” LaBr3 :Ce detectors were coupled to the AFRODITE array as their fir
 st in-beam experiment. AFRODITE consisted of eight HPGe clover detectors a
 s well two 3.5” x 8” LaBr3:(Ce) detectors. A dE-E particle telescope w
 as used to select the desired reaction channel. All detectors were used co
 njunction with the 16 channel all-digital waveform acquisition card\, PIXI
 E16.\nThe reaction of interest 45Sc(p\,d)44Sc was carried out at a beam en
 ergy of 27MeV. Through this reaction\, excited states that have lifetimes 
 which are apt for the characterization of the 2” x 2” LaBr3 :Ce detect
 ors were populated. One of the nuclei of interest in this work\, 44 Sc\, h
 as states with a wide range of lifetimes at low to moderate energies. Vari
 ous techniques such as the slope method and the centroid shift method have
  been employed to extract the lifetimes of excited states. All these endea
 vours will seek to unveil the quadrupole moment of nuclei and their intrin
 sic behaviour.\n\nhttps://indico.tlabs.ac.za/event/82/contributions/1336/
