| Abstract: | From the DWBA analysis of the angular distributions of the emitted deuterons populating the ground (E∗ = 0.0 MeV; 3/2−) and the first excited (E∗ = 0.429 MeV; 1/2−) states of 7Be, the ANCs for the 6Li+p→ 7Be system were deduced. Furthermore, the recently measured 6Li(p, γ ) 7Be reaction cross sections [Piatti et al., Phys. Rev. C 102, 052802 (2020)] were also analyzed within this theoretical framework. Excellent agreement was found between ANC values derived indirectly and those determined from the direct data, which strengthens the conclusion of the present work. The astrophysical S factor—at energies characterizing the Sun—for the 6Li(p, γ ) 7Be reaction was calculated using the weighted mean of the experimentally derived ANC values. Conclusions: The result of the present comprehensive study supports the extrapolation of Piatti et al. [Phys. Rev. C 102, 052802 (2020)], Dong et al. [J. Phys. G Nucl. Partic. 44, 045201 (2017)], and Gnech and Marcucci [Nucl. Phys. A 987, 1 (2019)], and thus disfavors the conclusions drawn by He et al. [Phys. Lett. B 725, 287 (2013)] and Xu et al. [Nucl. Phys. A 918, 61 (2013)]. |
