摘 要: | 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)).
