Abstract

The Feshbach and R-matrix approaches to nuclear structure calculations in the continuum have been applied to the elastic scattering of neutrons from ¹²C below the inelastic threshold. A simple shell model has been used for the positive-parity states of ¹³C and in contrast to the work of Lovas, the predictions of this model disagree significantly with experiment for both theories. The results for the two reaction theories have been compared.
