Résumé : We investigate three-a continuum states in the hyperspherical formalism for J = 0+ and J = 2+. We use the shallow Ali-Bodmer potential and the deep potential of Buck et al. We determine the 3a phase shifts up to E = 6 MeV, in parallel with an analysis of resonances in the framework of the Complex Scaling method. We show that shallow potentials provide additional narrow resonances, in contrast with experimental data. Deep potentials, however, only give rise to broad resonances, and are more consistent with the data. © Published under licence by IOP Publishing Ltd.
