摘要：

The Mott-Schwinger potential arising from the interaction of the magnetic moment of a neutron incident upon an electric field (of Bi-209) is found to have a profound effect upon the elastic scattering cross sections and polarisations at 0.5, 14.5 and 24 MeV. These effects are evaluated by specific solution of the relevant Schrodinger equations (for 100 partial waves) and with the Born approximation used to define the influence upon all higher ones. These 'exact' results agree with the estimations made under approximation in the past, but not with 'exact' results calculated by a different method.
