Optical-Model Analysis of the Elastic Scattering of Protons on a 9Be Nucleus, Including the Resonant Contribution

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

An optical-model analysis is performed for experimental data on the elastic scattering of protons on a 9Be nucleus in the 0.05–317 MeV range of energies. All available experimental data on the differential cross-sections of elastic scattering are analyzed along with data on the polarization and total cross-sections of the 9Be + p reaction. The OptModel program code with energy-dependent parameters of the optical potential is used with allowance for the resonance component of elastic scattering. Violation of the scattering matrix unitarity (the sum of the optical-model and resonance components) is observed at separate energy points and is no higher than 15%.
