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 Jπ = 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 T = 14 MeV. The possible existence of an excited state in the triton, which was predicted from a H(6He,α) experiment, is also discussed.
