In the framework of α+ α+ Λ three-body cluster model, we calculate energy spectra from bound energy region to resonant energy region up to around 20 MeV with respect to ααΛ threshold. To calculate resonant states, we employ Complex Scaling method which is one of the powerful method. We obtain the states of 8 Be analogue and genuine hypernuclear analogue, which are consistent with those by Yamada et al. (Prog Theor Phys Suppl 81:104, 1985). However, the calculated ordering of 9 Be analogue states is quite different with their calculation. We also obtain 2 + and 4 + resonant states of which have been never pointed out.
