Abstract
A collaborative research project has been launched on neutron-induced light-ion production measurements using the new Uppsala neutron beam facility. The available energy range of quasi mono-energetic neutron beams is extended up to 175 MeV. Double-differential cross sections (DDXs) of light-ion production (p, d, t, 3He, and α) are measured using a conventional spectrometer system which consists of eight counter telescopes. Each telescope is composed of two silicon surface barrier detectors as the ΔE detectors and a CsI(Tl) scintillator as the E detector. Response of the scintillators to 160 MeV protons is measured to test the performance. The measured response is reproduced well by a PHITS transport calculation. The DDXs of light-ion production are measured for Ca at 94 MeV and C at 175 MeV at angles between 20° to 160° in steps of 20°. The preliminary experimental (n,xp) data are shown in comparison with a model calculation using the TALYS code and the evaluated cross sections in the JENDL high-energy file.
