Strange (K) nuclear systems (S=-1)
Λ(1405) is considered as a superposition of two resonances instead of a simple bound state of the kaon and proton. Within the framework of the Brueckner-Hartree-Fock(BHF) theory, we have investigated the K nuclear systems (S=-1), especially K- pp and K- pnn(T=1). The binding energy BK-is 23 MeV (3 MeV) and the width Γ is 62 MeV (56 MeV) for K-pp(K-pnn(T=1)).
