摘要：
A 2(-) level at 3.0 MeV in B-8 has been suggested from Be-7 + p elastic scattering measurements. The effect of such a level on the low-energy 7Be(p, gamma)B-8 S factor is discussed, using R-matrix formulae with parameter values chosen to fit Li-7 + n data. It is concluded that the level must be broad (Gamma(0) greater than or equal to 4 MeV). (C) 2000 Elsevier Science B.V. All rights reserved.
