Lane-consistent, semimicroscopic nucleon-nucleus optical model - art. no. 024607

A semimicroscopic. Lane-consistent optical model is established up to 200 M eV for nucleons incident on spherical and near-spherical nuclei with masses 40 less than or equal toA less than or equal to 209. This model, based on the earlier approach of Jeukenne, Lejeune, and Mahaux in nuclear matter, is an extension of our previous work [E. Bauge, J. P. Delarochel and M. Girod , Phys. Rev. C 58, 1118 (1998)]. The modulus of the isovector potential is extracted and compared with measurements and fully microscopic predictions. Good overall descriptions of nucleon scattering, of transitions to isobari c analog states, and of reaction observables are obtained down to 1 keV. Th ose results are discussed in detail.
