We investigated the reaction dynamics induced by the ⁷Be,⁸B+²⁰⁸Pb collisions at energies around the Coulomb barrier. Charged particles originated by both the col- lisions were detected by means of 6 ΔE-E_res telescopes of a newly developed detector array. Experimental data were analysed within the framework of the Optical Model and the total reaction cross-sections were compared together and with the ^6,7Li+²⁰⁸Pb colli-sion data. According to the preliminary results, ⁷Be nucleus reactivity is rather similar to the ⁷Li one whereas the ⁸B+²⁰⁸Pb total reaction cross section appears to be much larger than those measured for reactions induced by the other weakly-bound projectiles on the same target.
