[en] The results of the analysis of the α-particle transfer "1"2C(d, "6Li)"8Be and "1"2Be("3He, "7Be)"8Be reactions at the low energies performed within the modified DWBA have been presented. New estimates are obtained for values of the asymptotic normalization coefficients (ANCs) for α+"3He → "7Be (g.s.) and α+"3He → "7Be (E"∗ = 0.429 MeV) as well as of the astrophysical S_3_4(0) factors for the direct capture "3He(α, γ)"7Be reaction.
