    Summary. The double-folding (DF) formalism of the α-nucleus optical potential is used and appropriate effective nucleon-nucleon (NN) interaction and alpha-particle density distribution at low energies are obtained by analysis of the α-α scattering at energies <35 MeV. Next a semi-microscopic DF analysis for the α-particle elastic scattering on A~100 nuclei at energies <32 MeV was carried out. The energy-dependent phenomenological imaginary optical model potential was obtained making also use of the dispersive correction to the microscopic real potential.

    Summary. Within the double folding (DF) formalism of the alpha-nucleus optical potential, used previously for a semi-microscopic analysis of the α-particle elastic scattering on A~100 nuclei at energies <32 MeV, effects due to changes of the nuclear density at finite temperature are considered. Parameterizations of the DF real potential as well as of regional phenomenological potential were used in the (n,α) reaction study for the target nuclei 92Mo, 95Mo, 98Mo, 100Mo.

    Summary. Analysis of the elastic scattering of deuterons on 6,7Li for energies <50 MeV was carried out using a phenomenological optical potential (OP). Energy-dependent average parameters of the OP were obtained in the analysis of the corresponding real and imaginary volume integrals, pointing out an "anomalous" behavior of the real potential when the imaginary part approaches zero. The coupled reaction channels method was also used to describe the 6Li(d,d0)6Li experimental angular distributions and proves the present OP reliability, at variance with global OP extrapolation.

    Summary. A previously derived semi-microscopic analysis based on the Double Folding Model, for alpha-particle elastic scattering on A similar to 100 nuclei at energies below 32 MeV, is extended to medium mass A~50--120 nuclei and energies from similar to 13 to 50 MeV. The energy-dependent phenomenological imaginary part for this semi-microscopic optical model potential was obtained including the dispersive correction to the microscopic real potential, and used within a concurrent phenomenological analysis of the same data basis. An ultimate assessment of (α,γ), (α,n), and (α,p) reaction cross sections considered target nuclei from 45Sc to 118Sn and incident energies <12 MeV.

    DOI: 10.1016/S0375-9474(01)00810-7

    Summary. The reliability of realistic M3Y effective NN interactions to describe multistep direct (MSD) processes is proved by analyzing the related real optical potentials (OP). This trial is done in order to overcome the uncertainties of the effective NN-interaction strength V0 obtained by fit of experimental data. The microscopic OP for nucleon-nucleus scattering at energies <50 MeV was calculated using nucleonic and mesonic form factors. It results that the strongly simplified model interactions used in MSD reaction theory neglect important dynamical details of such processes.

    DOI: 10.1103/PhysRevC.79.027601

    Summary. The results of two recent papers concerning (α,γ) and (α,n) reaction cross sections close to the reaction thresholds are discussed with regard to predictions of a recent α-particle regional optical potential (OP). The new measured cross sections are rather well described especially for the dominant reaction channels. Particular features of the α-particle OP below Coulomb barrier explain the failure of a former regional OP obtained by analysis of elastic scattering at higher energies.

    Summary. We show that new experimental data reported by Galaviz et al. [Phys. Rev. C 71, 065802 (2005)] can be used to improve a previous optical potential global parameter set, employing the corresponding former local parameter basis as well as the parameter sets obtained by a similar analysis of the new data.

    Summary. New results of (α,γ) and (α,n) reaction cross section measurements close to the reaction thresholds support the setting up of recent parameters of the α-particle optical model potential (OMP) below the Coulomb barrier. Particular features of the α-particle optical potential at energies below the Coulomb barrier explain the failure of using t

    Summary. An analysis of available α-particle-induced reaction cross sections on nuclei in the mass number range 121<A<197, below the Coulomb barrier, is carried out. An optical potential that describes the α-particle elastic scattering at low energies as well and both elastic-scattering and reaction data for 45<A<124 was thus obtained. The energy dependence of the surface imaginary potential depth is proved to be essential for understanding of α-particle interaction at these energies.

    DOI: 10.1103/PhysRevC.82.037601

    Summary. Experimental elastic-scattering angular distributions for deuteron interaction with 63Cu and 93Nb targets are compared with calculations performed within the continuum-discretized coupled-channels (CDCC) method, coupling to breakup channels being explicitly considered. The calculated elastic breakup is compared with the prediction of empirical parametrization for a wide energy range. It results that CDCC method permits the assessment of empirical parametrizations.he OMP parameters obtained by analysis of only α-particle elastic scattering at higher energies.
