Аннотация
In three-body models of halo nuclei such as ${}^{6}\mathrm{He},$ Pauli blocking is needed to remove components of the halo wave function that would disappear under full antisymmetrization. We compare a full projection-operator method with two others presently used for the purpose. A range of differences is found, small for bound states and resonances but larger for nonresonant continuum states. We indicate discriminating characteristics sensitive to the off-shell behavior.
