A theoretical framework of coupled-channels antisymmetrized molecular dynamics that describes the multistrangeness system with mixing between different baryon species is developed and applied to Λ12C and Ξ12Be. By introducing a minor modification to the YN G-matrix interaction derived from the Nijmegen model-D, the low-lying level structure and production cross section of Ξ12C are reasonably described. It is found that the low-lying states of Ξ12Be are dominated by the 11B?Ξ- channel and their order strongly depends on ΞN effective interactions used in the calculation. The calculated peak position of the production cross section depends on the ΞN effective interaction and the magnitude of spin-flip and non-spin-flip cross sections of K-p→K+Ξ- elemental processes. We suggest that the 12C(K-,K+)Ξ12Be reaction possibly provides us information about the ΞN interaction. [ABSTRACT FROM AUTHOR]

We provide a microscopic global optical potential (MGOP) for nucleon-nucleus (N A) 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 nonempirical way, from two kinds of microscopic mean-field models: the relativistic-mean-field (RMF) and Skyrme-Hartree-Fock + BCS (HF+BCS) models. We calculate the N A 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 22O, 24O, and 56Ni targets to compare the experimental data and then the cross sections for unknown 48S, 100Zr, and 110Zr are presented for future measurements. For the sake of convenience, the real and imaginary parts of the central and spin-orbit components of the N A 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/~takenori.furumoto/] with a program source file for reconstructing the MGOP. [ABSTRACT FROM AUTHOR]
