Light radioactive nuclear beams at LNL

Abstract

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, 17F and 8B, were produced with very low contaminant background and with an intensity of $\sim\kern-3pt 10^6$ and $\sim\kern-3pt 10^4$ pps, respectively. In the first measurement performed with the EXOTIC facility we studied the elastic scattering and the two-body breakup process of the 17F radioactive beam on a 208Pb target at Elab=86MeV. Preliminary results of this experiment, aiming at the investigation of the reaction mechanisms of the loosely bound 17F nucleus at subbarrier energies, show a rather small two-body breakup cross section.
