Optical model analyses have been carried out for nucleon-induced reactions on medium and heavy nuclei from 1 keV up to 200 MeV. The coupled-channels method based on the rigid-rotator model has been employed as an initial approach. It has been found that the coupled-channels analyses are indispensable to obtain a global formulation of optical potential. In addition, the coupled-channels calculation based on the soft-rotator model has been applied to analyses for various even-even fission product isotopes. They reproduced measured cross sections better than the rigid-rotator model in many cases. Though the latter is our ongoing study, we show the advantage of coupled-channels calculations and the applicability of the soft-rotator model.
