    "abstract": "I show that off-shell effects, like antisymmetrization and Be-7 distortions,\ncan significantly influence the energy dependence of the nonresonant\nBe7(p,gamma)B8 astrophysical S factor at higher energies. The proper treatment\nof these effects results in a vitrually flat E1 component of the S factor at\nE_cm = 0.3-1.5 MeV energies in the present eight-body model. The energy\ndependence of the nonresonant S factor, predicted by the present model, is in\nagreement with the low-energy direct capture data and the existing high-energy\nCoulomb dissociation data. Irrespective of whether or not the present energy\ndependence is correct, off-shell effects can cause 15--20% changes in the value\nof S(0) extrapolated from high-energy (E_cm \u003e 0.7 MeV) data.",
