Résumé : We study the Coulomb breakup cross section of the22C nucleus and its relation with three-body resonances and ground state properties. Cross sections are computed with a Coulomb corrected four-body eikonal model and they are constructed by fixing the continuum state and varying the ground state of22C. These states are calculated by using20C-n potentials that provide different scattering lengths and resonance energies, of a presumed virtual state and of a d resonance in21C. We find that the breakup cross section is strongly dependent on the ground state properties and we predict the existence of a 2+ narrow resonance in22C.
