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

Abstract

Gamma-ray production cross sections were measured for Al(n, xγ) and Cu(n, xγ) reactions at neutron energy of 5.3 MeV using the Dynamitron accelerator. A Ge (Li) detector was used for the γ-ray 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 7924, 811 keV for Al and 32 lines ranging of 6672, 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.
