Microscopic global optical potential for nucleon-nucleus systems in the energy range 50–400 MeV

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 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 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 22 O, 24 O, and 56 Ni targets to compare the experimental data and then the cross sections for unknown 48 S, 100 Zr, and 110 Zr 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/∼ takenori.furumoto/] with a program source file for reconstructing the MGOP.

“…In other (p, p ′ ) analyses for the T =0 1 + state in the same en-ergy range the Love and Franey interaction [30] was employed for the effective interaction. It was found that the calculated cross sections overestimated the data by a factor of 2 at forward angles [23,24,31]. From the studies, however, the origin of the discrepancy could be identified neither in terms of the nuclear structure nor the effective interaction.…”

Three-body dN interaction in the analysis of the 12C(,d′) reaction at 270 MeV

We have measured the cross sections and analyzing powers A y and A yy for the elastic and inelastic scattering of deuterons from the 0 + (g.s.), 2 + (4.44 MeV), 3 − (9.64 MeV), 1 + (12.71 MeV), and 2 − (18.3 MeV) states in 12 C at an incident energy of 270MeV. The data are compared with microscopic distorted-wave impulse approximation calculations where the projectile-nucleon effective interaction is taken from the three-nucleon t-matrix given by rigorous Faddeev calculations presently available at intermediate energies. The agreement between theory and data compares well with that for the (p, p ′ ) reactions at comparable incident energies/nucleon.Light-ion-induced inelastic scattering at bombarding energies above 100 MeV/nucleon is an appealing probe of nuclear structure due to the simple reaction mechanism. In such an energy domain, the reaction proceeds predominantly through a single step, and the distorted-wave impulse approximation (DWIA) gives a reasonable starting point for the theoretical description of data.

We perform a parameter-free calculation for the high-energy proton-nucleus scattering based on the Glauber theory. A complete evaluation of the so-called Glauber amplitude is made by using the factorization of the single-particle wave functions. The multiple-scattering or multistep processes are fully taken into account within the Glauber theory. We demonstrate that proton-12 C, 20 Ne, and 28 Si elastic and inelastic scattering (J π = 0 + → 2 + and 0 + → 4 + ) processes are very well described in a wide range of the incident energies from ∼ 50 MeV to ∼ 1 GeV. We evaluate the validity of a simple one-step approximation and find that the approximation works fairly well for the inelastic 0 + → 2 + processes but not for 0 + → 4 + where the multistep processes become more important.As an application, we quantify the difference between the total reaction and interaction cross sections of proton-12 C, 20 Ne, and 28 Si collisions.
