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.

A coupled-channel code to calculate nuclear cross sections, OPTMAN, has been improved after OPTMAN version 8 was published as JAERI-Data/Code 2005-002. The most important addition is the inclusion of dispersive relationships between imaginary and real parts of the optical potential within a Lane consistent formalism. The obtained CCOM potentials allow for the description of nucleon induced reactions up to 200 MeV, including (p,n) reactions with excitation of isobaric analog states. Relativistic corrections consistent with those used in the ECIS06 code are also added.
