摘要：

An extension for odd-A actinides of a previously derived dispersive coupled-channel optical model potential (OMP) for U-238 and Th-232 nuclei is presented. It is used to fit simultaneously all the available experimental databases including neutron strength functions for nucleon scattering on Th-232, U-233,U-235,U-238 and Pu-239 nuclei. Quasi-elastic (p,n) scattering data on Th-232 and U-238 to the isobaric analogue states of the target nucleus are also used to constrain the isovector part of the optical potential. For even-even (odd) actinides almost all low-lying collective levels below 1 MeV (0.5 MeV) of excitation energy are coupled. OMP parameters show a smooth energy dependence and energy independent geometry.
