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.1-8openAccessresonanceberyllium 9lithium 8 beamsbeamsmatrix materialsradioactive ion beamsdeuteron reactionsproton reactionsStudy of high lying resonances in 9Be by the measurement of (p,p), (p,a) and (p,d) reactionsArtigo de periódico22328110.22323/1.281.02230000-0003-4817-5275https://orcid.org/0000-0003-4817-5275Sem Percentil
