    "abstract": "We carry out Faddeev calculations of three-alpha (3 alpha) and two-alpha plus\nLambda (alpha alpha Lambda) systems, using two-cluster resonating-group method\nkernels. The input includes an effective two-nucleon force for the alpha alpha\nresonating-group method and a new effective Lambda N force for the Lambda alpha\ninteraction. The latter force is a simple two-range Gaussian potential for each\nspin-singlet and triplet state, generated from the phase-shift behavior of the\nquark-model hyperon-nucleon interaction, fss2, by using an inversion method\nbased on supersymmetric quantum mechanics. Owing to the exact treatment of the\nPauli-forbidden states between the clusters, the present three-cluster Faddeev\nformalism can describe the mutually related, alpha alpha, 3 alpha and alpha\nalpha Lambda systems, in terms of a unique set of the baryon-baryon\ninteractions. For the three-range Minnesota force which describes the alpha\nalpha phase shifts quite accurately, the ground-state and excitation energies\nof 9Be Lambda are reproduced within 100 - 200 keV accuracy.",
