A new analysis of the modern astrophysical S factors for the direct-capture 3 He(α, γ ) 7 Be reaction, precisely measured in recent works [B.S. Nara Singh et al., Phys. Rev. Lett. 93, 262503 (2004); D. Bemmerer et al., ibid. 97, 122502 (2006); F. Confortola et al., Phys. Rev. C 75, 065803 (2007), Gy. Gyrky et al., ibid. 75, 035805 (2007), T. A. D. Brown et al., ibid. 76, 055801 (2007), and A. Di Leva, et al., Phys. Rev. Lett. 102, 232502], has been carried out within the modified two-body potential approach. New estimates are obtained for the "indirectly determined" values of the asymptotic normalization constants and the respective nuclear vertex constants for 3 He + α → 7 Be(g.s.) and 3 He + α → 7 Be(0.429 MeV) as well as the astrophysical S factors S 34 (E) at E 90 keV, including E = 0. The values of asymptotic normalization constants have been used to obtain the values of the ratio of the α-particle spectroscopic factors for the mirror ( 7 Li 7 Be) pair.

“…In some cases the quality of description of data is not high enough in the initial variant of OCM. Other versions of OCM (presented in [9,10] for example) utilize the phenomenological local potential in contrast to direct one and explore two alternative ways to take into account the Pauli exclusion principle: 1. Two-body model with forbidden states which are eigenstates of the Hamiltonian.…”

Algebraic version of the orthogonality conditions model is developed by analogy with the algebraic version of the resonating group model. It is shown that all exchange terms excluding ones originated by the exchange kernel of the potential energy can be easily taken into account in the frame of the formalism of the version. The potential term as a whole is modelled phenomenologically. Both direct algebraic approach and the method basing on the solution of the integro-differential Schrödinger equation containing nonlocal terms related to the forbidden and the semi-forbidden states are proposed. This equation turns out to be preferable in studies of narrow resonances. It is demonstrated that decay width of a system into two-heavy-fragment channel is strongly affected by the nonlocal terms.
