高温pp链中,入射道涉及α的反应是使得高温pp反应链成为除3α过程外合成CNO种子核的另一种机制的关键反应。其中~7Be(α,γ)~(11)C和~8B(α,p)~(11)C的反应率依赖于~(11)C、~(12)N等核的α粒子发射阈附近能级的性质。由于在现有条什下直接测量技术难度较大,目前这两个反应都缺乏相关的实验数据。因此,通过间接方法得到相关的共振能级性质,间接研究其反应率,就显得非常必要。另一方面,由于3α过程的反应率受到~(12)Cα粒子发射阈以上能级性质的影响,~(12)C的高激发
High-temperature pp chain, the entrance channel involved in α response is to make high-temperature pp reaction chain in addition to 3α process outside the synthesis of CNO seed nuclear another key reaction mechanism. The reaction rates of ~ 7Be (α, γ) ~ (11) C and ~ 8B (α, p) ~ (11) C depend on the vicinity of the α particle emission threshold of ~ (11) C, ~ The nature of the level. Due to the difficulty of direct measurement techniques under existing regulations, there is currently no relevant experimental data for both reactions. Therefore, it is very necessary to obtain the related resonance energy level by indirect method and indirectly study the reaction rate. On the other hand, since the reaction rate of 3α process is affected by the energy level above the emission threshold of ~ (12) Cα particles, the high excitation of ~ (12) C
