研究了在低能量下进行核反应的有效野外理论。在Gamow-Peak Energy上$^{12} $ c捕获的辐射$α$ capture的天体物理$ s $ s $ - $ t_g = 0.3 $ MEV，是核胃物理学的基本数量，我们为反应构建了一个eft。要修复有效的拉格朗日式出现的参数，将EFT应用于三种反应的研究：弹性$α$ - $^{12} $ c散射在低能量下，$ e1 $辐射$α$ capture on $^{12} $ c的过渡$^{12} $ c，以及$β$ deled $β$ deled $α$α$α$α$ n $^$^$ n}}}}}}}}}}}}}}}}}}}}} 16}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}。我们报告了$ s_ {e1} $的估计 - 通过使用EFT，通过$ t_g $的$ e1 $过渡的反应因子。我们还讨论了EFT在低能量下对核反应的应用。
An effective field theory (EFT) for a nuclear reaction at low energies is studied. The astrophysical $S$-factor of radiative $α$ capture on $^{12}$C at the Gamow-peak energy, $T_G=0.3$ MeV, is a fundamental quantity in nuclear-astrophysics, and we construct an EFT for the reaction. To fix parameters appearing in the effective Lagrangian, the EFT is applied to the study for three reactions: elastic $α$-$^{12}$C scattering at low energies, $E1$ transition of radiative $α$ capture on $^{12}$C, and $β$ delayed $α$ emission from $^{16}$N. We report an estimate of the $S_{E1}$-factor of the reaction through the $E1$ transition at $T_G$ by employing the EFT. We also discuss applications of EFTs to nuclear reactions at low energies.
