| Summary: | We solved the Faddeev equations in the Λnn system Jπ = ½+, 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 E = 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)i MeV. We discuss importance of an irreducible three-body force to make it bound. |
