Within the framework of the modified potential cluster model with the classification of orbital states according to Young diagrams, the possibility of description experimental data for S-factor of the proton radiative capture on 7Li to the ground state of 8Be is considered. It was shown that taking into account E1 and M1 transitions from the state of p7Li scattering to the ground state of 8Be in the p7Li channel it is possible to explain the value of the S-factor at energies up to 10 MeV. Based on the calculated total cross sections, the reaction rate in the temperature range of 0.01 to 10.0 T9 is obtained. It is demonstrated that the inclusion of low-lying resonance states gives some contribution into the reaction rate at high temperatures.

7Li(p,γ)8Be 低能辐射捕获反应速率

在根据杨氏图对轨道状态进行分类的修正势簇模型的框架内,考虑了描述7 Li 到8 Be基态的质子辐射捕获的S因子的实验数据的可能性。结果表明,考虑到E 1 和M 1 从状态的转变7Li 散射到8 Be的基态7Li 通道可以解释能量高达 10 MeV 时S因子的值。基于计算的总截面,在 0.01 到 10.0 温度范围内的反应速率9获得。结果表明,包含低共振态对高温下的反应速率有一定的贡献。
