Abstract: The Λ*-hypernuclei, which are bound states of Λ(1405) and nuclei, are studied as a possible interpretation of the K-nuclei. The Bonn and Nijmegen potentials are extended and used as a phenomenological potential between Λ* and N. The K-exchange potential is also considered in the interaction of Λ* and N. The two-body (Λ*N) and three-body (Λ*NN) systems are investigated using a variational method. It is shown that the spin and isospin of the ground states are given by Λ*N (S = 1, I = 1/2) and Λ*NN (S = 3/2, I = 0), respectively. The binding energies of the Λ*-hypernuclei are compared with experiment.
