Résumé : We present the results of the 8Li(p,α) 5He transfer reaction, measured at the RIBRAS facility. It was performed in inverse kinematics using a thick CH 2 polyethylene target. The complete excitation function was measured between E cm=0.4-2.7 2MeV, which includes the Gamow peak energy region. The excitation function was reproduced with the R-matrix theory. © 2011 American Institute of Physics.
