Description

Performed an optical-model analysis (description) of proton elastic scattering at 50 keV to 200 MeV proton energy Ep on 6,7Li and 9Be nuclei. There was used an optical-model code OptModel (developed at RFNC-VNIIEF) where resonance part of elastic scattering was taken into account. Energy dependences of optical potential parameters from [2] with our modifications were used. All obtainable data on differential and total cross sections and polarization were analyzed simultaneously. Evaluated data from ENDF/B-VII, SaBa [3] were used as well as experimental ones. The interruption of the scattering matrix unitarity was observed at several energetic points and was no more than 7%. Energy dependences of volume real potential radius rV, diffuseness aV and amplitude VV of 6Li+p reaction are shown in fig. 1 (a-c). 6Li+p and 9Be+p reaction total cross sections are demonstrated in fig. 2,3.
