Abstract

The structures of the ground and excited states of 11Be were studied with a microscopic method of antisymmetrized molecular dynamics. The theoretical results reproduce the abnormal parity of the ground state and predict various kinds of excited states. We suggest a new negative-parity band with a well-developed cluster structure which reaches high-spin states. Focusing on a 2α cluster structure, we investigated the structure of the ground and excited states. We point out that molecular orbits play important roles for the intruder ground state and the low-lying 2ħω states. The features of the breaking of α clusters were also studied with the help of data for Gamow-Teller transitions.
