摘要：

We present a global spherical optical model potential for neutrons with incident energies from 1 keV up to 200 MeV containing dispersive terms and a local energy approximation. A comprehensive database for spherical or quasispherical nuclei covering the mass range 24less than or equal toAless than or equal to209 is used to automatically search on all parameters. A good representation of the entire data set is obtained when both volume and surface potentials share the same energy-independent geometry.
