Résumé : The 11Li breakup on a 208Pb target is studied in the Coulomb corrected eikonal approximation by using a 9Li+n+n three-body description of the projectile. The 11Li wave functions are defined in the hyperspherical formalism for bound and scattering states, and are obtained from effective 9Li+n and n+n interactions. The 9Li+n+n three-body phase shifts suggest the existence of a narrow 1- resonance near 0.5 MeV above threshold. This resonance shows up as a peak in the breakup cross section, and is supported by experimental data.
