Abstract
Tissue is primarily composed of elements such as hydrogen, carbon, oxygen, and nitrogen. Nitrogen has the largest neutron capture cross section among these elements. In a nitrogen neutron capture reaction (NNCR), an energetic proton is emitted, which quickly loses its energy along its track. It is expected that such released energy will be deposited within the tissue under consideration. Therefore, even though nitrogen only makes up approximately 3% of tissue by mass, its effect is significant and cannot be ignored. In this work, the neutron capture reaction by 14N is simulated using the GEANT4 toolkit to characterize the reaction in terms of kinematical quantities. In future work, we will be able to study the effects associated with the final state of the NNCR that might take place in tissue.
