A study of the mechanisms involved in the production of alpha particles from
reactions induced by a 6He radioactive beam on a 9Be light target, is presented. The
experimental data was obtained using the RIBRAS (Radioactive Ion Beams in Brasil) facility
of the Institute of Physics of the University of São Paulo, Brazil [1, 2]. The RIBRAS system
consists of two superconducting solenoids used to select and focus light secondary beams of
nuclei far from the stability line. A high yield of α-particles has been observed in the
measurement performed for the 6He+9Be system [3], which was not present with the gold
target, used for normalization purposes. In the present work, the energy and the angular
distributions of those events have been analysed. The results will be compared with
theoretical calculations performed using the Ichimura-Austern-Vincent (IAV) formalism, a
new model recently applied to study inclusive reactions [4,5].
