A Dispersive, lane-consistent coupled-channel optical model based on soft-rotator theory for accurate calculation of nuclear reaction data

Chiba, Satoshi; Soukhovitski, E. Sh.*; Capote, R.*; Quesada, J.*

Coupled-channels optical model code OPTMAN is widely applied to analyze experimental nucleon-nucleus interaction data. Sophisticated dispersive optical potential forms had been included in the code along with the possibility to calculate direct excitations of isobar analog states in (p,n) reactions. The latter along with accounting of the proton "effective" energy decrease due to Coulomb repulsion by nuclei, leads to full Lane-consistent optical potential. Such approach had been successfully applied to nucleon-nucleus interaction reaction analyses of experimental data for several nuclei up to 200 MeV incident energies.
