    Nuclear potential models

    Optical potentials are an essential ingredient in theories for nuclear reactions [1]. They characterize initial and final states, determine transmission coefficients and often provide the terms needed for transition operators responsible for the reaction. Over the last decade, significant progress has been made in obtaining optical potentials from ab-initio many-body calculations (e.g. [2,3])....

    Nuclear potential models

    After nearly sixty years since its introduction, the phenomenological bell-shape Perey–Buck spatial nonlocality in the optical model potential for nucleon–nucleus scattering has remained unaccounted for from a microscopic standpoint. In this article we provide a quantitative account for such nonlocality considering fully nonlocal optical potentials
    in momentum space. The framework is based...

    Nuclear potential models

    A microscopic description of the nucleus-nucleus reaction system has been attempted.
    The double-folding model with effective nucleon-nucleon interaction is widely successful to describe nucleus-nucleus scatterings.
    However, we need a special prescription for the microscopic description of the $\alpha$-nucleus scatterings, for example for the application of the strong renormalization factor...

  4. 20. Nuclear reaction cross sections and the optical potentials for the n-$^{12}$C and N-$^{12}$C scattering

    Nuclear potential models

    Realistic nuclear reaction cross-section models are an essential ingredient of reliable heavy-ion transport codes. Such codes are used for risk evaluation of manned space exploration missions as well as for ion-beam therapy dose calculations and treatment planning \cite{luoni}.
    Within the community of basic research in nuclear reactions, reaction cross section data compared to theoretical...
