We present the results of total fusion cross sections measurements for the 6;7Li + 27Al, 9Be + 27Al, systems at energies above and below the Coulomb barrier (0.8 Vb < E < 2.0 Vb). The experimental evidence at the measured energy regime show that the total fusion cross sections of 6Li and 9Be with a light mass target are not affected by the break-up process. The elastic break up cross sections for the 6Li + 27Al system were also measured and the results are being presented in this issue. The data for the 7Li + 27Al system are still being analyzed and therefore these results should be considered preliminary.
