C/O Kerma coefficient ratio for 96 MeV neutrons deduced from microscopic measurements

Double-differential cross sections for neutron-induced light-ion production at 96 MeV have been measured for a variety of nuclei at The Svedberg Laboratory. Using the measured cross-section data, we deduce the Kerma coefficient from carbon and oxygen for p, d, t,3He and α particles. In order to get...
