High-energy gamma rays resulting from low-energy nuclear reactions in light nuclei

摘要

Products resulting from 3.02 MeV deuterons incident on a natural boron target have been investigated byway of gamma-ray spectroscopy and activation analysis. This study uses observed gamma rays and cascades to deduce the populated states from the reaction products. Die-away measurements are included to investigate the built-up activation from the target and compared with tabulated half-lives to further understand the plethora of reactions taking place. Many of the observed gamma rays, such as 15.1 MeV, result from the formation of excited states of C-12, while others are secondary and tertiary processes from alpha breakup resulting in Be-8.
