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