Abstract We construct a phenomenological -KN interaction which reproduces the two resonances: the energy of the first resonance is 1420MeV and the other is
1392MeV. The λ(1405) is found by a superposition of the two resonances with appropriate weights. Within the framework of the Brueckner-Hartree-Fock theory, we have studied K--3He(T=0) and K--4He(T=1/2). The binding energy BK- is 93MeV(72MeV) and the width Γ is 13MeV(25MeV) for K--3He(T=0) (K--4He(T=1/2)).
