We present the new facility EXOTIC at Legnaro National Laboratories (LNL), dedicated to the in flight production of light exotic beams at near-barrier energies. The radioactive beams are produced via inverse kinematics mode of intense TANDEM beams hitting on light gas targets. The first beams, F-17 and B-8, were produced with very low contaminant background and with an intensity of similar to 10(6) and similar to 10(4) pps, respectively. In the first measurement performed with the EXOTIC facility we studied the elastic scattering and the two-body breakup process of the F-17 radioactive beam on a Pb-208 target at E-lab= 86MeV. Preliminary results of this experiment, aiming at the investigation of the reaction mechanisms of the loosely bound F-17 nucleus at subbarrier energies, show a rather small two-body breakup cross section.
