The α-⁷Li and α-¹²C Elastic Scattering at E_α=5. and 6. MeV

Abstract

The differential cross sections of α-⁷Li and α-¹²C elastic scattering have been measured at energies E_α=5 and 6 MeV. The results are interpreted by using real phase-shift analysis. It has shown that the real phase-shifts interpreted the α-¹²C scattering data very well at the energies investigated. The α-⁷Li scattering data are also fitted quite good by the real phase-shifts. The states at E_x=0.4776 MeV in ⁷Li and at E_x=4.439 MeV in ¹²C play little role in this experiment. For scattering angles θ_C.M.>150°, the results are found to show very prominent glory scattering and fit to the glory model very well.
