在独立α集团模型下 ,利用扭曲波冲量近似 (DWIA) ,计算了实验室系下入射能量为 10 1 5MeV的敲出反应1 6 O(p ,pα) 1 2 C和实验室系下入射能量分别为 90MeV和 14 0MeV的敲出反应1 6 O(α ,2α) 1 2 C .得到的反应截面和谱因子与实验数据基本符合 ,比用壳模型的结果有了一定的改进 ,表明独立α集团模型能较好地描述α集团敲出反应的机理 Under the independent α-group model, the knock-out reaction 1 6 O (p, pα) 1 2 C with the incident energy of 10 1 5MeV and the incident energy under the laboratory were calculated by using the distorted wave impulse approximation (DWIA) The reaction cross sections and spectral factors were basically consistent with the experimental data, and the results were better than the shell model, indicating that the independent α (α, 2α) The group model can better describe the mechanism by which the alpha group knocks out the reaction
