Using the microscopic optical potential model to analyze 10,11Be elastic scattering on protons and nuclei

Abstract

The density distributions of 10,11Be nuclei obtained via the generator coordinate method (GCM) and quantum Monte Carlo (QMC) model are used to calculate the microscopic optical potentials (OP) and elastic scattering cross sections of these nuclei on protons and the 12C nucleus. The real part of the OP is obtained by means of folding while the imaginary part is estimated within a high-energy approximation. The depths of the real and imaginary parts of OP are varied by fitting these calculations to experimental data on cross sections. The known energy dependence of the respective volume integrals of potentials is used to resolve ambiguities in magnitudes of these depths. These OPs can be applied to the further calculations of the cross sections of different reactions in which they take part.
