论文摘要
在修改的潜在群集模型的框架内，根据年轻图的分类，考虑了关于7LI中中子辐射捕获的总横截面的实验数据的可能性。结果表明，使用的模型和构造电势的方法使得可以正确描述5 MeV（5 10-3 eV）至1 MeV至1 MeV（1 10+6 eV）的实验横截面的行为，其中有实验数据。基于获得的总截面高达5 MeV，计算了反应速率，并进行了分析近似。结果表明，7Li（N，G）8LI反应在T9 <0.1-0.2时占主导地位，而反应7Li（3H，N）9BE和7LI（4HE，G）11b中的7Li燃烧。
Within the framework of the modified potential cluster model with forbidden states and their classification according to Young diagrams, the possibility of describing experimental data on the total cross sections of the neutron radiative capture on 7Li is considered. It is shown that the model used and the methods for constructing potentials make it possible to correctly describe the behavior of experimental cross sections at energies of 5 meV (5 10-3 eV) to 1 MeV(1 10+6 eV), where experimental data are available. Based on the obtained total cross sections up to 5 MeV, the reaction rate was calculated and its analytical approximation was carried out. It was shown that the 7Li(n,g)8Li reaction dominates at T9 < 0.1-0.2 as against with the burning of 7Li in reactions 7Li(3H,n)9Be and 7Li(4He,g)11B.
