Résumé : Coulomb breakup has been proposed as an indirect technique to infer radiative-capture cross sections at low energies. To test this idea we have performed the Flubber experiment at the FRIBs facility of the Laboratori Nazionali del Sud (Catania, Italy). In this experiment, we have measured the breakup of 17F on lead at 40AMeV. The motivation of this measurement is reported as well as preliminary experimental data.
