Gamma-Ray Production Cross Sections for Aluminum and Copper at 5.3-MeV Neutron Energy

Gamma-ray production cross sections were measured for AI(n, x γ)and Cu(n, xγ)reactions at neutron energy of 5.3 MeV using the Dynamitron accelerator. A Ge(Li) detector was used for the γray detection and data were obtained for emission angle of 55°. Absolute differential production cross sections of discrete γ-ray lines were presented with probable origins of the transitions. The measured γ-rays were 17 lines ranging of 792∼4,811 keV for Al and 32 lines ranging of 667∼2,330 keV for Cu. The experimental results were compared with previous measurements. The present results are relatively large for Al and agreement is fair for Cu.
