    "abstract": "The previous Faddeev calculation of the two-alpha plus Lambda system for 9\nLambda Be is extended to incorporate the spin-orbit components of the SU_6\nquark-model baryon-baryon interactions. We employ the Born kernel of the\nquark-model Lambda N LS interaction, and generate the spin-orbit component of\nthe Lambda alpha potential by the alpha-cluster folding. The Faddeev\ncalculation in the jj-coupling scheme implies that the direct use of the\nquark-model Born kernel for the Lambda N LS component is not good enough to\nreproduce the small experimental value Delta E^exp_{ls}=43 +- 5 keV for the\n5/2^+ - 3/2^+ splitting. This procedure predicts three to five times larger\nvalues in the model FSS and fss2. The spin-orbit contribution from the\neffective meson-exchange potentials in fss2 is argued to be unfavorable to the\nsmall ls splitting, through the analysis of the Scheerbaum factors for the\nsingle-particle spin-orbit potentials calculated in the G-matrix formalism.",
