| Popis: | 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. Načinili smo račune Faddeevom metodom u konfiguracijskom prostoru za nakupinski model ααΛ hiperjezgre 9 ΛBe primjenom različitih potencijala. Za nuklearnu sastavnicu međudjelovanja αα primijenili smo samo fenomenološki Ali-Bodmerov potencijal. Energiju vezanja hiperjezgre 9 ΛBe smo računali dvama različitim potencijalnim modelima. U prvome se rabi s-valni potencijal αΛ koji djeluje na sve parcijalne valove u podsustavu αΛ. U drugome, rabi se nov realističniji potencijal αΛ koji sadrži s- i p-parcijalne sastavnice. Proučavali smo također učinak sredice u potencijalu αα. |
