Fusion reactions involving radioactive beams at GANIL

The ISOL type SPIRAL facility at GANIL has been commissioned recently and delivers radioactive beams (RIBs) for physics since a couple of years. Despite many difficulties arising from both the complexity to produce good beam quality and intensity as well as to setup the appropriate detection system, the first experiments with SPIRAL have demonstrated that nuclear dynamics studies (nuclear structure and low energy reaction mechanism) at the Coulomb barrier are possible with that kind of beams. RIBs like $^{76}$Kr and $^{6,8}$He have been used to produce exotic nuclei via fusion evaporation or to study reaction mechanisms at low energy. These two examples will be detailed in this talk
