中文摘要：

利用同位旋依赖的尼尔逊势,在宏观-微观理论框架下,计算了幻数N=28同中子链上原子核的性质,研究了N=28同中子链上原子核的形变和形状共存现象.研究结果表明,N=28这个幻数在Na,Mg,Al同位素链上有着强的形状共存现象.此外,计算表明42Si的基态为扁椭球,同时在Si同位素链上的形状共存现象相对较弱.

英文摘要：

With the isospin-dependent Nilsson potential,we calculate the properties of the N = 28 nuclei in the framework of macroscopic-microscopic model.The shape and shape coexistence of these nuclei are calculated and discusses.It is shown that strong shape coexistences occur in the ground state of nuclei with N = 28 in Na,Mg and Al isotopes.It is pointed out that,the ground state of 42Si is oblate shape and there is no obvious shape coexistence for 42Si.
