本文研究了E_1和E_2多极对C-12(α，γ(O))O-16反应的干扰效应。阐明了伽马射线角分布、E_1和E_2俘获相以及C-12+α弹性散射相移之间的关系。对2.68 MeV共振附近的能量和角度相关效应进行了详细的研究，发现了一个新的实验特征。此外，还讨论了质心运动和伽马射线偏振的影响。
This paper investigates interference effects involving the E1 and E2 multipole contributions to the C-12 (alpha, gamma (o)) O-16 reaction. The relationships between gamma -ray angular distributions, E1 and E2 capture phases, and C-12 + alpha elastic scattering phase shifts are clarified. A detailed study of the energy- and angle-dependent effects near the 2.68-MeV resonance is presented, where a new experimental signature has been identified. In addition, the effects of center-of-mass motion and gamma -ray polarization are discussed.
