Description

The dispersion relation is included into the optical potential. Compared with the common coupled-channel optical model, the number of potential parameters is greatly reduced. The coupled-channel method based on the soft rotator model is used to analyze the nucleon scattering by a deformed 28Si nucleus. A set of the optical potential parameters is obtained, and the numerical results show a good agreement with the available experimental data of neutron total cross sections, neutron/proton elastic and inelastic angular distributions.
