Abstract:The neutron yield of thick targets of carbon, natural and enriched in 13 C, bombarded by deuterons of 20 and 30 MeV has been measured by the activation method. The gain with respect to a 12 C target is the same as with protons beams. The yield ratio is about 1.2 only and hardly can justify the use of a 13 C target with deuteron beams. The data, apart from being of interest for the design of facilities where secondary neutron beams are used, provide a test case for calculations where both beam and target have a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
