【摘要】 The angle-differential cross sections of neutron-induced deuteron production from carbon were measured at six neutron energies from 25 to 52 MeV relative to those of n-p elastic scattering at the China Spallation Neutron Source（CSNS） Back-n white neutron source.By employing the ΔE-E telescopes of the Light-charged Particle Detector Array（LPD A） system at 15.1° to 55.0° in the laboratory system,ratios of the angle-differential cross sections of the 12C（n,xd） reactions to those of the n-p scattering were measured,and then,the angle-differential cross sections of the 12C（n,xd） reactions were obtained using the angle-differential cross sections of the n-p elastic scattering from the JENDL-4.0/HE-2015 library as the standard.The obtained results are compared with data from previous measurements,all of which are based on mono-energic neutrons,the evaluated data from the JENDL-4.0/HE-2015 library and the ENDF-B/Ⅷ.0 library,and those from theoretical calculations based on INCA code and Talys-1.9 code.Being the first white-neutron-source-based systematic measurement of the angle-differential cross sections of neutron-induced deuteron production reactions on carbon in several tens of MeV,the present work can provide a reference to the data library considering the lack of experimental data.
