Analysis of protonBe9,10,11,12 scattering using an energy, density, and isospindependent microscopic optical potential
Abstract
The proton elastic scattering of ^{9,10,11,12}Be isotopes at a wide energy range from 3 to 200 MeV/nucleon is analyzed using the optical model with the partialwave expansion method. The microscopic optical potential (OP) is taken within the singlefolded model. The density and isospindependent M3YParis nucleonnucleon (NN) interaction is used for the real part and the NNscattering amplitude of the highenergy approximation is used for the imaginary one. The surface contribution to the imaginary part is included. The analysis reveals that the partialwave expansion with this microscopic OP reproduces well the basic scattering observables at energies up to 100 MeV/nucleon. For higher energies, the eikonal approximation with the same OP gives results better than the partialwave expansion calculations. The volume integrals of the OP parts have systematic energy dependencies, and they are parameterized in empirical formulas. In addition, the volume integral's parametrizations determine the true energy dependence for the depths of the OP parts. The study of increasing the number of neutrons for a given isotope shows that the imaginary volume integrals and reaction cross sections depend on the matter radii of the scattered nuclei. Further, they are found to have larger values for the halo nucleus scattering (Be11+p) than those for the scattering of their isotopes.
