“…3) The total alpha production cross section measured by gas mass spectrometry, which had no minimum detection energy limit, was 894 AE 60 mb with 14.8 MeV neutron incidence, 26) which is considerably larger than ours. The present modeling, however, reproduces both DDXs for neutrons and -particles consistently within their measured energy ranges.…”

We carried out a detailed measurement of the neutron-induced -particle emission double-differential cross section of carbon at 14.2 MeV, for which there are few measured data in spite of its importance in many applications. In our measurement, a superior S/N ratio, high angular/energy resolutions and a wide detection energy range were realized with a pencil DT neutron beam and a countertelescope system. The obtained cross section for the 12 C(n, 0 ) 9 Be (ground state) reaction agreed well with the results of previous experiments and evaluated nuclear data. The obtained angular-differential cross section of the 12 C(n,n 0 +3) reaction for -particles showed a strong forward-peaked distribution that suggested a significant contribution of the direct reaction process to the 3 breakup. We attempted to calculate the emitted particle spectra by a Monte Carlo method and estimate the branching ratio of the channels that contribute to the 12 C(n,n 0 +3) reaction. As a result, it was found that the 12 C(n,) 9 Be Ã channels play an important role in generating the experimental double-differential cross section both of emitted -particles and neutrons. The estimated ratio of the 12 C(n,) 9 Be Ã channels was approximately 40%, somewhat larger than those evaluated in previous studies.
