    "abstract": "A generalization of the Complex Shell Model formalism is presented which\nincludes antibound states in the basis. These states, together with bound\nstates, Gamow states, and the continuum background, represented by properly\nchosen scattering waves, form a representation where all states are treated on\nthe same footing. Two-particle states are evaluated within this formalism and\nobservable two-particle resonances are defined. The formalism is illustrated in\nthe well known case of $^{11}$Li in its bound ground state and in\n$^{70}$Ca(gs), which is also bound. Both cases are found to have a halo\nstructure. These halo structures are described within the generalized Complex\nShell Model. We investigated the formation of two-particle resonances in these\nnuclei, but no evidence of such resonances was found.",
