Abstract
Differential cross sections at 16.44 and 17.57 MeV and analyzing powers at 8.0, 9.1, 11.1, 13.5 and 15.0 MeV have been measured for the 9Be(p, n 0) 9B reaction and combined with previous measurements for 9Be(p, p 0) 9Be, 9Be(p, n 0) 9B and 9Be(n, n 0) 9Be to form the first model-complete data base for a Lane model analysis. Energy dependences of the model parameters (including Coulomb corrections) have been handled in a consistent manner. The real central part of the isovector Lane model potential exhibits no surface peaking for this nucleus. Strong evidence is found for a complex spin-orbit part of the isovector potential describing nucleon scattering from 9Be.
