We present the results of the Li-8(p,alpha)He-5 and Li-8(p, p)Li-8 reactions measured at the RIBRAS (Radioactive Ion Beams in Brazil) system. The experiment was realized in inverse kinematics using a thick [CH2](n) polyethylene target and an incident 8Li beam, produced by RIBRAS. Using the thick target method, the complete excitation function could be measured between E-cm = 0.2 -2.1 MeV, which includes the Gamow peak energy region. The excitation function of the Li-8(p,alpha)He-5 reaction, populating resonances between 16.888 and 19.0 MeV in Be-9, was obtained[1] and the resonances were fitted using R-matrix calculations. This study shed light on spins, parities, partial widths and isospin values of high lying resonances in Be-9. The measurement of the resonant elastic scattering Li-8(p,p)Li-8 populating resonances in the same energy region can constrain the resonance parameters. Preliminary results of the elastic scattering are also presented. (AU) | |
