| Popis: | We provide a microscopic global optical potential (MGOP) for nucleon-nucleus (NA) systems in a wide range of nuclear mass numbers (A = 10-276) and incident energies (E = 50-400 MeV). The potential is microscopically constructed based on a single-folding (SF) model with the complex G-matrix interaction. The nuclear densities used in the SF model are generated, in a non-empirical way, from two kinds of microscopic mean-field models: the relativistic-mean-field (RMF) and Skyrme-Hartree-Fock BCS (HF-PBCS) models. We calculate the NA potentials for more than 1000 even-even nuclei with atomic number Z = 6-92, involving proton- and neutron-rich unstable nuclei. We confirm that both the MGOP models well reproduce the available experimental data of the total reaction cross sections, the total neutron cross sections, the elastic-scattering cross sections, the analyzing power, and the spin-rotation function Q. We also calculate the proton scattering cross sections of O-22, O-24, and Ni-56 targets to compare the experimental data and then the cross sections for unknown S-48, Zr-100, and Zr-110 are presented for future measurements. For the sake of convenience, the real and imaginary parts of the central and spin-orbit components of the NA potentials are respectively represented in a linear combination of 12-range Gaussians. They are provided on the website [http://www2.yukawa.kyoto-u.ac.jp/similar to takenori.furumoto/] with a program source file for reconstructing the MGOP. |
