Abstract
Fits are made to low-energy 9Be(γ,n)8Be cross-section data using one-level R-matrix formulae including channel contributions. Fits with reasonable parameter values are found for the newer radioactive-isotope data, and also for data obtained from inelastic electron scattering on 9Be, but not for older radioactive-isotope data. This differs from the result of recent fits using a semi-microscopic model, which supported the older data. The difference is attributed to the use in the latter calculation of a single-particle potential description of the continuum wave function.
