The newly developed cerium tribromide (CeBr 3 ) detector has reduced intrinsic gamma-ray activity with gamma energy restricted to 1400-2200 keV energy range. This narrower region of background gamma rays allows the CeBr 3 detector to detect more than one gamma ray to analyze the gamma-ray spectrum. Use of multiple gamma-ray intensities in elemental analysis instead of a single one improves the accuracy of the estimated results. Multigamma-ray detection capability of a cylindrical 75 mm × 75 mm (diameter × height) CeBr 3 detector has been tested by analyzing the chlorine concentration in water samples using eight chlorine prompt gamma rays over 517 to 8578 keV energies utilizing a D-D portable neutron generator-based PGNAA setup and measuring the corresponding minimum detection limit (MDC) of chlorine. The measured MDC of chlorine for gamma rays with 517-8578 keV energies varies from 0.07 ± 0.02 wt% to 0.80 ± 0.24. The best value of MDC was measured to be 0.07 ± 0.02 wt% for 788 keV gamma rays. The experimental results are in good agreement with Monte Carlo calculations. The study has shown excellent detection capabilities of the CeBr 3 detector for eight prompt gamma rays over 517-8578 keV energy range without significant background interference.

Triton production cross section has been measured in interaction of 200-350 keY deuteron with l3e nuclei. In this study excitation functions of l3C(d, t)12e reaction have been measured at eight angles in 10 keY energy steps over 200-350 keY deuteron energy range while angular distributions of l3C(d, t)l2e reaction were measured at 200, 250, 270,290, 310, 330 and 350 keY deuteron energies. The angular distributions of l3C(d, t)l2e reaction are forwardpeaked and are in disagreement with shape of previously reported data of l3C(d, t)l2e reaction at 4lO keY deuteron energy. On the contrary the shape of angular distribution measured in this study has a better agreement with the shape of angular distribution of l3C(d, t) 12 e reaction at 410 keY deuteron calculated using zero-range Distorted Wave Born Approximation (DWBA) model.
