Resonant states of 9ΛBe with α plus α plus Λ three-body cluster model

We study the structure of(Lambda)( 9)Be within the framework of the three-body alpha + alpha + Lambda cluster model using the YNG-NF interaction with the Gaussian expansion method. We obtain the energies of bound states as well as energies and decay widths of the resonant states with the complex scaling method. By analyzing our wave functions of bound states and resonant states, we confirm three analog states of Be-9(Lambda) pointed out by Bando and Motoba et al. [T. Motoba, H. Bando, and K. Ikeda, Prog. Theor. Phys. 70, 189 (1983); T. Motoba, H. Banda, K. Ikeda, and T. Yamada, Prog, Theor. Phys. Suppl. 81, 42 (1985); H. Bando, K. Ikeda, and T. Motoba, Prog. Theor. Phys. 69, 918 (1983)1, Be-8 analog states, Be-9(Lambda) genuine states, and Be-9 analog states. The new states of Be-9(Lambda) are also obtained at a high energy region with broader decay widths.
