We search for three-neutron resonances which were predicted from pion double charge exchange experiments on {sup 3}He. All partial waves up to {ital J}=5/2 are nonresonant except the {ital J}{sup {pi}}=3/2{sup +} one, where we find a state at {ital E}=14 MeV energy with 13 MeV width. The parameters of the mirror state in the three-proton system are {ital E}=15 MeV and {Gamma}=14 MeV. The possible existence of an excited state in the triton, which was predicted from a H({sup 6}He,{alpha… Expand
