【摘要】An 6 Li+89Y experiment was conducted at the Laboratori Nazinali di Legnaro,INFN,Italy.The 550 μg/cm2 thick 89Y target was backed on a 340 μg/cm2 thick 12C foil.The several γ rays in the experiment with energies higher than 3000 keV can most likely be ascribed to the transitions in the 13C nuclei,which can be formed through various interactions between the 6 Li beam and the 12C foil.The high-energy properties of γ rays in 13C are employed for energy calibrating HPGe detectors,especially for the> 3000 keV region,which is impossible to reach by common standard sources(152Eu,133Ba,etc.).Furthermore,γ-γ and particle-γ coincidence measurements were performed to investigate the formation of 13C.
