Abstract: | The data for the 7Li + 9Be and 7Be + 9Be elastic scattering at the energies E
lab(7Li) = 15.75 , 24, 30, 34, 63 and 130MeV and E
lab(7Be) = 17 , 19 and 21MeV were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic
scattering, reorientation of 7Li , 7Be and 9Be as well as most important transfer reactions were included in the coupled-channels scheme. The resulting 7Li and 7Be potentials are very similar and have the same energy dependence. The real potential for recently derived 8Be + 9Be scattering potentials is very similar to that for 7Li , 7Be but the imaginary part of the 8Be one has a much greater strength at longer range. |
