We search for three-neutron resonances which were predicted from pion double charge exchange experiments on 3He. All partial waves up to J=5/2 are nonresonant except the J^\mathrm\ensuremathπ=3/2+ one, where we find a state at E=14 MeV energy with 13 MeV width. The parameters of the mirror state in the three-proton system are E=15 MeV and \ensuremathΓ=14 MeV. The possible existence of an excited state in the triton, which was predicted from a H(6He,\ensuremathα) experiment, is also discussed. \textcopyright 1996 The American Physical Society.
