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 EP- VC in the proton channel.
