The Mott-Schwinger effect in neutron elastic scattering from {sup 209}Bi

Abstract

The Mott-Schwinger (MS) potential arising from the interaction of the magnetic moment of a neutron incident upon an electric field (of {sup 209} Bi) is found to have a profound effect upon the elastic scattering cross sections and polarisations at 0.5, 14.5 and 24 MeV. Those effects are evaluated by specific solution of the relevant Schroedinger equations (for 100 partial waves) and with the Born approximation used to define the influence upon all higher ones. The actual calculated phase shifts and how the scattering amplitudes can be formed are then presented. One of the outcome of this study is the development of a fast and accurate method for evaluating scattering observables and wave functions with the inclusion of the MS potential in the Schroedinger equation. The formalism and methods may be now applied in analyses of (p, n) and other reactions in which the MS interaction potential could be significant. 14 refs., 2 tabs., 4 figs.
