The proton capture on ${}^3$H is important to understand various physical and astrophysical processes. In this study, the cross section and astrophysical S-factor of the proton radiative capture on triton were taken into account at low energies. The ${}^3$H(p,${\gamma )}^4$He reaction was studied using the E1 transition. The gamma-ray transition is dominated by the E1 multipolarity and by incoming $\mathit{p}$-waves. The non-resonant astrophysical S-factors for the E1 transition were calculated using the potential model. The results were satisfactorily in good agreement with the corresponding experimental data.

Triton上质子辐射俘获的天体S因子

质子捕获 ${}^3$H对于理解各种物理和天体过程很重要。在这项研究中，在低能量条件下考虑了质子辐射俘获tri的截面和天体S因子。这${}^3$生命值，${\gamma ）}^4$使用E1跃迁研究了他的反应。伽马射线跃迁主要由E1多极性和入射$\mathit{p}$-波浪。使用电位模型计算E1跃迁的非共振天体S因子。结果令人满意地与相应的实验数据吻合。
