Abstract

The structures of the ground and excited states of ¹²Be were studied with antisymmetrized molecular dynamics. The ground state was found to be a state with a developed 2\ensuremathα core with two neutrons occupying the intruder orbits. The energy levels of the newly measured spin-assigned states were described well, except for the 1₁^\ensuremath- state. The calculations indicated that many exotic cluster structures appear in the low-energy region. The widths concerning \ensuremathα and ⁶He decays were discussed by using reduced width amplitudes.
