摘要：

The Lambda*-hypernuclei, which are bound states of A(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 Lambda* and N. The K-exchange potential is also considered in the interaction of Lambda* and N. The two-body (Lambda*N) and three-body (Lambda*NN) systems are investigated using a variational method. It is shown that the spin and isospin of the ground states are given by Lambda*N(S = 1, I = 1/2) and Lambda*NN(S = 3/2, I = 0), respectively. The binding energies of the Lambda*-hypernuclei are compared with experiment.
