Sažetak

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