Аннотация
The results of the analysis of the new experimental astrophysical S factors S exp 24 (E) [D. Trezzi, et al., Astropart. Phys. 89 , 57 (2017)] and those measured earlier [R. G. Robertson, et al., Phys. Rev. Lett. 47 , 1867 (1981)] for the nuclear-astrophysical d(α,γ) 6 Li reaction directly measured at extremely low energies E , are presented. New estimates and their uncertainties have been obtained for values of the asymptotic normalization coefficient for α + γ → 6 Li and for the direct astrophysical S factors at Big Bang energies.
