Abstract：
Particle radiative capture cross sections of ¹²C(n,γ) and ¹²C(p,γ) have been calcaulated at 90° in the neutron energy range of 5—25MeV and proton energy range of 8—35MeV. Pigmy resonance exists at the excitation energy E_x=13MeV in ¹²C(n,γ) reaction. The dips observed at the excitation energy around 11.74MeV and 14.06MeV in ¹²C(p,γ) reaction are attributed to the destructive interference between semidirect capture and fine resonance capture in the process of doorday state. The calculations agree with expermental results.
