Abstract：
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 ¹²C and ¹⁶O have been calculated and the density distributions demonstrate an equilateral triangle 3α clustering for ¹²C 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.
