中文摘要：

The α-cluster structures for 12C and 16O are investigated in the framework of the covariant density functional theory,where the pairing correlation is treated with a particle number conserving shell-model-like approach.The ground states of 12 C and 16 O have been calculated and the density distributions demonstrate an equilateral triangle 3α clustering for 12 C and a regular tetrahedron 4α clustering for 16O.The existence of linear nα chain structure of both 12C and 16O is revealed at high quadrupole deformation.

英文摘要：

The α-cluster structures for 12^C and 16^O are investigated in the framework of the covariant density functional theory, where the pairing correlation is treated with a particle number conserving shell-model-like approach. The ground states of 12^C and 160 have been calculated and the density distributions demonstrate an equilateral triangle 3α clustering for 12^C and a regular tetrahedron 4α clustering for 16^O The existence of linear nα chain structure of both 12^C and 16^O is revealed at high quadrupole deformation.
