Abstract: A 6Li + 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/cm 2 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 6Li 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.
