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 15O+p+p→17Ne+γ is considered as an illustration.

双质子辐射俘获的渐近归一化系数法

渐近归一化系数方法是研究核天体物理学中双体非共振辐射俘获过程的标准方法。该方法建议对天体物理学感兴趣的低能量区域中的辐射捕获截面进行全面的分析描述。我们演示了如何将此方法推广到三体 2p 辐射捕获的情况。发现该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体问题的复杂性。辐射捕获 15O+p+p→17Ne+γ 被认为是一个例证。
