The quantal flux behaviors of the refractive process in the elastic scattering of16O at 1503 MeV

Abstract

The quantal flux behaviors of the refractive process in the elastic scattering of [Formula: see text] on different targets at 1503 MeV are analyzed based on the eikonal approximation. For their angular distributions, the optical model and the eikonal approximation calculations are performed and compared with each other. The shadow-surface decomposition is carried out to qualitatively assess the strength of the surface scattering relative to the shadow one. The transversal fluxes are calculated and negative values representing the refractive process are observed near the nuclear surface region. The peak value of the negative region is found capable of being a characteristic quantity to measure the strength of the refractive scattering. The transversal-flux-peak orbital angular momentum increases as the target mass number increases and can be a quantity characterizing the refraction. The corresponding impact parameter is found closer to the outer part of the potential surface region.
