Small lab tests were performed by the York group on a 1.5" LaBr3:Ce detector with a241Am/9Be Alpha source. The report that followed is based on theself-activity of the crystal as well as the effects of neutronactivation on the detector. It was determined that the majority ofgamma emission in the spectra after neutron activation were due toexcited states of La and Br (140La, 80Br and 82Br). The crystals werealso tested to see if Pulse Shape Discrimination was possible. It wasfound that (n,gamma)discrimination was not possible. The report can be found here.
