Study of the Li(d, xn) reaction for the development of accelerator-based neutron sources

Abstract

Double-differential neutron production cross sections (DDXs) for deuteron-induced reactions on Li at 200 MeV were measured for emission angles ranging from 0◦ to 25◦ in steps of 5◦ by means of a time of flight (TOF) method with EJ301 liquid organic scintillators at the Research Center for Nuclear Physics (RCNP), Osaka University. The measured DDXs were compared to theoretical model calculations with the DEURACS and PHITS codes and TENDL-2017 nuclear data. It was found that the DEURACS calculation is in better agreement with the measured DDXs than the PHITS calculation, while TENDL-2017 fails to reproduce both the spectral shape and magnitude of the measured DDXs for all angles.

Neutron production in the interaction of 200-MeV deuterons with Li, Be, C, Al, Cu, Nb, In, Ta, and Au

“…Moreover, the experimental data are compared with theoretical model calculations with PHITS (Particle and Heavy Ion Transport System) [9] and DEURACS (Deuteron-induced Reaction Analysis Code System) [10], and the latest nuclear data (JENDL-5 [3] and TENDL-2021 [4]) as benchmark tests. It should be noted that the result of Li has already been reported in ND2019 [11].…”
