Energy Calibration Of Hpge Detector Using The High-Energy Characteristic Gamma Rays In C-13 Formed In Li-6+C-12 Reaction

An Li-6 + Y-89 experiment was conducted at the Laboratori Nazinali di Legnaro, INFN, Italy. The 550 mu g/cm(2) thick Y-89 target was backed on a 340 mu g/cm(2) thick C-12 foil. The several gamma rays in the experiment with energies higher than 3000 keV can most likely be ascribed to the transitions in the C-13 nuclei, which can be formed through various interactions between the Li-6 beam and the C-12 foil. The high-energy properties of gamma rays in C-13 are employed for energy calibrating HPGe detectors, especially for the > 3000 keV region, which is impossible to reach by common standard sources (Eu-152, Ba-133, etc.). Furthermore, gamma-gamma and particle-gamma coincidence measurements were performed to investigate the formation of C-13.
