摘要：
We solved the Faddeev equations in the Ann system (J(pi) = 1/2(+) T = 1). There is no bound state but found a resonance state. Complex Energy Method helps to find the location of the resonance energy in the complex.Riemann sheet. We obtained a resonance energy L' 0.25 - 0.40i MeV using the realistic NN and YN Nijmegen potential. As a preliminary result the recent Nijmegen YN potential (NSC97f) gives 0.60 +/- 0.05- (0.25 +/- 0.05)1 MeV We discuss importance of an irreducible three-body force to make it bound
