Abstract：
The structure of nucleus ¹¹Be is investigated in terms of Particle-Vibrator Model (PVM).The low-lying states and electro-dipole transition of the first excied state to ground state of ¹¹Be are calculated,and the results are in good agreement with experiments.The calculated wave-function of the ground state of ¹¹Be shows that the parity inversion was caused by coupling of single particle motion with collective vebration of cove( ¹⁰Be.The halo structure of ¹¹Be is also explained reasonably in terms of the PVM.
