We construct a phenomenological (K) over barN interaction which reproduces the two resonances: the energy of the first resonance is 1420MeV and the other is 1392 MeV. The (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- - He-3(T = 0) and K- - He-4(T = 1/2). The binding energy B-K- is 93MeV(72 MeV) and the width Gamma is 13 MeV(25 MeV) for K - He-3(T = 0) (K - He-4(T = 1/2)).
