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

Abstract

Products resulting from 3.02-MeV deuterons incident on a natural boron target have been investigated by way 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 to 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 12 C, while others are secondary and tertiary processes from α breakup resulting in 8 Be.

“…Although Geant4 is capable of modeling LENRs, we use previously published experimental data to generate our beam source. Measurements were taken at MIT’s Bates Accelerator facility with both LaBr and HPGe detectors, and the details of the experiment and characterization of the beam were carried out by Rose et al [16, 26]. To create the source input for Geant4, an in-house γ -ray unfolding code was used to unfold the measured LaBr spectrum [27].…”
