The proton microscopic optical potential (MOP) based on Skyrme interaction has been achieved by the Green function method in the nuclear matter, and given by the local density approximation (LDA) for finite nuclei. The reaction cross-sections, elastic scattering angular distributions, analyzing powers, and spin-rotation functions are predicted by the obtained proton MOP with Skyrme interaction SkC in the mass range of target nuclei 24[Formula: see text][Formula: see text][Formula: see text]A[Formula: see text][Formula: see text][Formula: see text]209 with incident proton energy below 100[Formula: see text]MeV. These observables are further predicted for some light nuclei and actinide nuclei below 100[Formula: see text]MeV. The prediction is compared with existing experimental data. It is revealed that the obtained proton MOP based on Skyrme interaction SkC can satisfactorily describe the proton–nucleus elastic scattering.

The neutron microscopic optical potential (MOP) based on Skyrme interaction has been achieved by the Green function method in the nuclear matter, and given by the local density approximation (LDA) for finite nuclei. The total cross-sections, nonelastic cross-sections, elastic scattering angular distributions and analyzing powers are predicted for some light nuclei and actinide nuclei below 100[Formula: see text]MeV by the obtained neutron MOP with the Skyrme interaction SkC. These data are also predicted for targets in the mass range of [Formula: see text] which are too deformed and have rich nuclear structure properties. All of the theoretical results give reasonable agreements with the corresponding experimental data.

AbstractThe elastic scattering in the reaction $$^{7}$$ 7 Li+$$^{208}$$ 208 Pb was investigated in the bombarding energy range from 25 to 39 MeV. The real and imaginary parts of the optical potential were analyzed by using a phenomenological potential. A dispersion relation analysis is presented in order to investigate the threshold anomaly effect. It is concluded that $$^{7}$$ 7 Li has an intermediate behavior between the tightly bound nuclei such as $$^{16}$$ 16 O and the loosely bound nuclei such as $$^{6}$$ 6 Li where the lack of the threshold anomaly is unambiguously observed. Reaction cross sections are also extracted from the elastic scattering data and its comparison with the ones of other systems has been performed to draw hints on the effect of the breakup channel.

Microscopic Optical Potential

The nucleon scattering on even–even nuclei in the medium-energy region has been analyzed on the basis of microscopic optical potential (OP) obtained from nuclear-matter calculations with using effective density-dependent nucleon–nucleon interaction of Skyrme type with taking account of the rearrangement potential. Calculations have been performed for volume integrals and rms radii of nucleon–nucleus OP, for energy dependencies of total and total reaction cross sections of neutron– and proton–nucleus scattering and for differential cross sections of the elastic neutron scattering at several energies on various target nuclei. Comparison of the calculation results for the mentioned quantities with corresponding experimental data has been carried out, which has shown a principal possibility of their reasonable description in the framework of the model under consideration.

Elastic scattering and total reaction cross sections (via y ray yields) have been measured for 160+ 12C in the c.m. energy range 5� 5-10,0 MeV. Some well-defined structure is observed, with peak widths of order 250 keV. An optical potential which fits peaks in the total reaction cross section is shown to be inadequate to explain the elastic scattering data. Possible reasons for this inconsistency, which imply the need for a more general optical potential, are discussed.

The MPI implementation of the calculation of the microscopic optical potential of nucleon-nucleus scattering within the single folding model has been developed. The folding potential and the corresponding differential cross section of the 11Li + p elastic scattering have been calculated at 62 MeV/nucleon on the heterogeneous cluster "HybriLIT" of the Multifunctional Information and Computational Complex (MICC) of the Laboratory of Information Technologies of JINR. The agreement between experimental data and numerical results for various models of the 11Li density distribution used in the construction of the folding potential is demonstrated

A new set of global phenomenological optical model potential (OMP) parameters for alpha projectile is obtained by simultaneously fitting the experimental data of reaction cross-sections and elastic scattering angular distributions in the mass range of target nuclei [Formula: see text] at incident energies below 386[Formula: see text]MeV. The total reaction cross-sections and elastic scattering angular distributions are calculated and compared with experimental data for different targets. A satisfactory agreement is presented between them.
