Title: Comparison between two methods of solution of coupled equations for low-energy scattering

Abstract

Cross sections from low-energy neutron-nucleus scattering have been evaluated using a coupled-channel theory of scattering. Both a coordinate-space and a momentum-space formalism of that coupled-channel theory are considered. A simple rotational model of the channel-interaction potentials is used to find results using two relevant codes, ECIS97 and MCAS, so that they may be compared. The very same model is then used in the MCAS approach to quantify the changes that occur when allowance is made for effects of the Pauli principle.
