The Energy Dependence of the Isospin Part of the Optical Potential
The possible energy dependence of the isospin part of the optical potential was suggested by Thurlow1 in her analysis of the (p,n) angular distributions obtained at a proton bombarding energy of 94 MeV by Langsford, et al.2 She observed that the depth of the isospin potential at 94 MeV was significantly shallower than the depth obtained from analysis of (p,n) data at lower energies. She concluded that this discrepancy could be accounted for by an energy dependence of the isospin potential. However, it was pointed out later that the shallow isospin potential at 94 MeV could be due to the poor knowledge of the optical parameters at this energy.3
