Dispersive coupled-channel analysis of nucleon scattering from 232 Th up to 200 MeV

An isospin-dependent coupled-channels optical model potential containing a dispersive term (including nonlocal contribution) is used to simultaneously fit the available experimental database (including strength functions and scattering radius) for neutron and proton scattering on strongly deformed 2...
