论文摘要
渐近归一化系数的方法是研究核天体物理学中两体非辐射捕获过程的标准方法。该方法提出了对天体物理兴趣低能区域中辐射捕获横截面的完全分析描述。我们演示了如何将这种方法推广到三体$ 2p $辐射捕获的情况下。发现此过程的一个基本特征是捕获的高度相关性。这反映了三体库仑连续性问题的复杂性。辐射捕获$ ^{15} $ o+$ p $+$ p \ rightarrow ^{\，17} $ ne+$γ$被视为插图。
The method of asymptotic normalization coefficients is a standard approach for studies of two-body non-resonant radiative capture processes in nuclear astrophysics. This method suggests a fully analytical description of the radiative capture cross section in the low-energy region of the astrophysical interest. We demonstrate how this method can be generalized to the case of three-body $2p$ radiative captures. It was found that an essential feature of this process is the highly correlated nature of the capture. This reflects the complexity of three-body Coulomb continuum problem. Radiative capture $^{15}$O+$p$+$p \rightarrow ^{\,17}$Ne+$γ$ is considered as an illustration.
