Configuration-space Faddeev calculations are performed for cluster model aaL of the 9LBe hypernucleus using various aL potentials. For the aa interaction, the nuclear component is only taken into account (phenomenological Ali-Bodmer potential). The binding energy of the 9LBe hypernuclei is calculated for two different potential models. In the first model, the s-wave aL potential acting in all partial waves in the aL subsystem is used. In the second model, a recent more realistic aL potential having the s- and p-partial components is employed. The core effect of nuclear aa potential is also studied.
