Abstract：
Using a new phenomenological KN interaction which reproduces Λ(1405) as an I=0 bound state of KN, we have investigated K^－－³ He(T=0) and K^－－⁴He(T=1/2) within the framework of the Brueckner-Hartree-Fock(BHF) theory. Our calculations show that the above kaonic nuclear systems are both deeply bound. The binding energy B_K－ is 124.4 MeV(94.1 MeV) and the width Γ is 11.8 MeV(25.8 MeV) for K^－－³He(T=0) (K^－－⁴He(T=1/2)).
