Exotic clustering investigation in 13B and 14C using RIBs

This contribution reports on the investigation about the existence of molecular and/or exotic cluster configurations in boron and carbon n-rich isotopes. To this aim two experiments were performed: the first experimental study of exotic 9Li + 4He cluster states in 13B using the resonance scattering method at TRIUMF, and, with the same technique, the measurement of 10Be + 4He scattering at LNS in Catania, where a 10Be radioactive beam was produced for the first time. In the case of 13B, the elastic excitation function shows the presence of various peaks in an excitation energy region never explored before. In the case of 14C, our exclusive measurement of elastic scattering data with a high intensity beam, sheds some light on previously published results which seemed to be in contradiction
