Résumé :

We present the results of the 8Li(p, α) 5He reaction of astrophysical interest, measured at the RIBRAS system. It was realized in inverse kinematics and using a thick CH 2 polyethylene target. Using the thick target method the complete excitation function could be measured between E cm=0.2-2.5 MeV, which includes the Gamow peak energy region. The contribution of contaminating 12C( 8Li, 4He) 16N and 12C( 7Li, 4He) 15N reactions is still under analysis. However, if the cross section is expected to be somewhat reduced, the subtraction of the contamination will not change the general feature of the excitation function. © 2012 American Institute of Physics.
