Three-Body Structure of $$^9_{\varLambda }$$Be with $$\alpha \alpha \varLambda $$ Cluster Model

Three-body resonant states of $^9_Λ$Be with $α+α+Λ$ cluster model

“…In Ref. [20], we found energies and ordering of some resonant states were consistent with those by Motoba et al, and some were different from results by Bandō and Motoba et al [1][2][3]. However, we have not analyzed three-types of category for states obtained in Ref.…”

“…For this purpose, recently, using CSM and Gaussian Expansion Method (GEM), we obtained all of possible resonant states of 9 Λ Be within the framework of α + α + Λ three-body model [20]. In Ref.…”

“…Therefore, in this work, we calculate energy spectra of bound states as well as of resonant states with the α + α + Λ three-body model + CSM using the same αΛ interaction as used in Ref. [20]. By comparing our wave functions with those of the SU(3) shell-model wave functions, we confirm that the 8 Be analogue states', 9 Be analogue states', and 'genuine states' appear, as discussed by Bandō and Motoba et al [1][2][3].…”

Structure of the ground and excited states in $_Λ^{9}$Be nucleus

“…In Table VI we display the spectrum of 9 Λ Be obtained in Refs. [39] and [40], and compare it with our results. As this nucleus has not more than two bound states and TABLE VI.…”

“…In Ref. [26] energy spectra of bound and resonance states of 9 Λ Be have been calculated within the framework of α + α + Λ three-body model. The α − α interaction was chosen so to reproduce the observed α − α scattering phase shift and the ground state of 8 Be within the α − α orthogonality condition model.…”
