Description of continuum structures in a discrete basis: Three-body resonances and two-nucleon decays

Description

Weakly bound and unbound three-body nuclei are studied by using the pseudostate method within the hyperspherical formalism. After introducing the theoretical framework, the method is applied first to the 9Be nucleus, showing a good agreement with the available data for its low-lying dipole response. Then, recent results on the structure and decay of the two-neutron emitters 26O and 16Be are presented. In particular, the role of the n-n correlation in shaping their properties is discussed.
