摘要：

The reaction C-14(alpha, gamma)O-18 has been measured in the alpha energy range of E(alpha) = 1.14-2.33 MeV. The resonance strengths of the 4+ resonance at E(alpha) = 1.14 MeV and of the 1- resonance at E(alpha) = 1.79 MeV have been measured relative to the C-14(p, gamma)N-15 resonance at E(p) = 0.528 MeV. Additionally, two nonresonant gamma-transitions to the ground state and to the first excited state of O-18 were found. The energy dependence of their cross sections can be described by the direct capture process and its interference with the two 1- resonances at E(alpha) = 1.79 and 2.33 MeV.
