Abstract: A spherical optical model potential (OMP) containing a dispersive term is used to fit the available experimental database of s(u) and sT for n127Al covering the energy range 0.1–250 MeV using relativistickinematics and a relativistic extension of the Schrödinger equation. A dispersive OMP with parameters that show a smooth energy dependence and an energy-independent geometry are determined from fits to the entire data set. A very good overall agreement between experimental data and predictions is achieved up to 150 MeV. Inclusion of nonlocality effects in the absorptive volume potential allows one to achieve an excellent agreement up to 250 MeV.
