Measurement of charged-particle emission DDX for carbon with 14-MeV incident neutrons

摘要

Measurement of the a-particle emission double differential cross-section (DDX) for carbon with 14-MeV incident neutrons is being carried out and a preliminary result was described in this paper. The agreement of our obtained DDX at the emission angle of 30 deg. with a previous data measured by Haight et al. was fairly well in the higher energy part, while a slight discrepancy was observed below 3 MeV. In order to investigate the mechanism of the ~(12)C(n,n'+3α) reaction, we tried to calculate the energy spectra of emitted particles by the Monte Carlo method considering reaction kinematics of a lot of channels which contribute to the reaction.
