英文摘要	A resonant state at 3.21(-0.04)(+0.12) MeV, located just above the one-neutron separation threshold, was observed for the first time in Be-12 from the Be-11(d, p) Be-12 one-neutron transfer reaction in inverse kinematics. This state is assigned a spin-parity of 0(-) according to the systematics of the level scheme of the N = 8 isotones and decay-width analysis. Gamow coupled-channel and Gamow shell-model calculations show the importance of the continuum coupling, which dramatically influences the excitation energy and ordering of low-lying states. Various exotic structures associated with cross-shell intruding configurations in Be-12 and in its isotonic nucleus Li-11 are comparably discussed.
