The Research Program at RIBRAS (Radioactive Ion Beams in Brasil)-III (original) (raw)

A part of the research program developed in the RIBRAS facility over the last four years is presented. Experiments using radioactive secondary beams of light exotic nuclei such as 6 He, 7 Be, 8 Li on several targets have been performed. Elastic angular distributions have been analysed by the Optical Model and four body Continuous Discretized Coupled Channels Calculations (4b-CDCC) and the total reaction cross sections have been obtained. A comparison between the reaction cross sections of 6 He and other stable projectiles with medium-heavy targets was performed. Measurements of the proton transfer reaction 12 C(8 Li, 9 Be) 11 B are also presented.
