The (p, p), (p, a) and (p, d) reactions on 8Li were measured at low energies. The experiment
was performed using a thick [CH2]n target and a radioactive 8Li beam available at the RIBRAS
facility of São Paulo . This experiment represents an upgrade of a previous experiment, where
only the 8Li(p,a)5He cross section was measured. High lying resonances of 9Be, which are
still uncertain, could be studied in this way. The detection of several reaction channels allows a
reliable determination of the resonance parameters, such as energy, width and spin-parity. In the
deuteron channel we could observe the same resonance decaying to d+7Ligs and to d+7Li∗. The
properties of the resonances are determined by a R-matrix analysis, which provides evidence for
a significant clustering as well in the (p, a) as in the (p, d) channels. The experimental data and
the multi-channel R-matrix analysis will be presented.
