Abstract

In order to investigate the existence of molecular and/or exotic cluster configurations in Boron and Carbon n-rich isotopes we undertook two experiments: the first experimental study of exotic Li-9+alpha cluster states in B-13 using the resonance scattering method at TRIUMF (Canada), and, with the same technique, the measurement of Be-10+alpha scattering at LNS in Catania, where a Be-10 radioactive beam was produced for the first time. In order to measure the excitation function in a wide energy range, the beams were stopped in a Helium-flooded chamber. In the case of B-13, the elastic excitation function shows the presence of various peaks in an excitation energy region never explored before. In the case of C-14, our exclusive measurement of elastic scattering data with a high intensity beam, sheds some light on the contradictory previously published results [1, 2].
