Resumen
We present the results of the 8Li(p,??)5He and 8Li(p,p)8Li 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 Ecm = 0.2 ??? 2.1 MeV, which includes the Gamow peak
energy region. The excitation function of the 8Li(p,??)5He reaction, populating resonances
between 16.888 and 19.0 MeV in 9Be, 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 9Be. The measurement of the resonant elastic
scattering 8Li(p,p)8Li populating resonances in the same energy region can constrain the
resonance parameters. Preliminary results of the elastic scattering are also presented. Funda????o de Amparo ?? Pesquisa do Estado de S??o Paulo (FAPESP) FAPESP: 11/15904-7
