Microscopic optical potentials for nucleon-nucleus $\mathrm{}\left(\mathrm{NA}\right)\mathrm{}$ scattering obtained from the folding of the effective g matrices, solutions of the Bruckner-Bethe-Goldstone equation, with the densities of the target, are applied to the case of neutron-nucleus scattering. Given that the optical potentials are specified in all two-body angular momentum, spin and isospin channels available to the $\mathrm{NA}$ scattering, the only difference in this model description of proton and neutron scattering observables for a given nucleus is in the inclusion of the Coulomb interaction. A priori microscopic optical model predictions for neutron and proton elastic scattering are compared with results from a phenomenological optical model and with data. New measurements are recommended to reduce discrepancies in the existing database, and to differentiate between different theoretical predictions.
