Résumé : We investigate continuum states of the α+n+n and α+p+p systems using a microscopic three-cluster model in the hyperspherical formalism. The A-nucleon wave functions are defined in the generator coordinate method (GCM). The R-matrix method is used to connect the wave functions to their exact asymptotic behaviors and to derive the collision matrix. We present the three-body phase shifts of the 0+ and 1- continuum of the α+n+n and α+p+p systems. © 2011 World Scientific Publishing Company.
