摘　　要：采用同位旋依赖的尼尔逊势,在宏观微观模型的理论框架下,计算考察了N=10同中子链和Z=13同位素链上原子核的结构和性质.重点考察了23Al的核结构.理论计算很好的给出了这些原子核的解核能和形变,讨论了23Al基态的自旋和宇称,结果表明形变对于理解23Al的结构和性质非常重要.此外,还讨论了轻核区可的晕结构和能级反转.The nuclear structures and properties of N=10 isotones and Z=13 isotopes are investigated in the frame-work of macroscopic-microscopic model with the isospin-dependent Nilsson potential. Special emphases are placed on the structures of ^23Al. The calculations well reproduce the experimental ground state binding energies and deformations of these nuclei. The ground state spin and parity of ^23Al are calculated and discussed. It is found that deformation plays an important role in understanding the nuclear structure of ^23Al. The possible halo structure and the level inversion in the light mass region are discussed.
