The progressive development of the scintillator detectors has made it possible to do direct electronic lifetime determination. The 2” x 2” LaBr₃:(Ce) detectors provide a combination of excellent time resolution and good energy resolution. With these detectors it is possible to do direct lifetime measurements of excited nuclear states up to a few hundred nanoseconds. Six 2” x 2” LaBr₃:(Ce) detectors were coupled to the AFRODITE array as their first in-beam experiment. AFRODITE consisted of eight HPGe clover detetectors as well two 3.5” x 8” LaBr₃ (Ce) detectors. A particle telescope was used to select the desired reaction channel. The reaction of interest ⁴⁵Sc(p,d) ⁴⁴Sc was carried out at a beam energy of 27MeV. Through this reaction, excited states that have lifetimes which are apt for the characterization of the 2” x 2” LaBr₃:(Ce) detectors were populated. One of the nuclei of interest in this work, ⁴⁴Sc, has states with a wide range of lifetimes at low to moderate energies.
