Abstract ：The potential energy surfaces and density distributions of ground states in even-mass Be isotopes are studied by using the point-coupling covariant density functional theory with the PC-F1 effective interaction. The clustering structure is exhibited automatically in most of the Be isotopes. The results indicate that 6 Be has an α +2p clustering structure, while 8,10,14 Be have the 2α clustering structure. The α –α distances and the corresponding quadrupole deformation parameters have a similar evolution trend against the neutron number.
