Abstract：
This paper researches resonance phenomenon in the fast neutron radiative capture reaction. ¹²C(n, γ₀) cross sections are calcaulated in the neutron energy range of 5-25 MeV and angular distribution is calcaulated at neutron energy 9MeV by DSD model. Reaction mechanism contains five terms: the compound nucleus capture, direct capture and semidirect capture, radiative capture in compound elastic and inelastic channels. The calculations display the pygmy resonance peak at excitation energy E_x=13MeV and the giant resonance peak at excitation energy E_x=21MeV. The calculations agree with exepermental results.
