Abstract
Recently derived isospin dependent optical model potentials (OMP) containing a dispersive term including non-local contribution are extended to cover 31 actinide nuclei of interest and several Ta- and W-isotopes. As low-lying collective levels of the studied nuclides and Fermi energies are well-known, we only needed to estimate their deformation parameters based on evaluated strength functions. New experimental scattering data are needed to confirm derived regional OMP parameterizations. Isovector components of the dispersive coupled-channel optical model potential for actinides have been challenged on available quasi-elastic (p, n)_IAS scattering data for ²³²Th and ²³⁸U nuclei. Reasonable agreement has been achieved. An exact Lane consistency of the dispersive OMP is discussed. Strict Lane consistency can be achieved by using newly derived formulae and Coulomb corrected energy E_P- V_C in the proton channel.
