The superheavy nuclei have been examined systematically in the region 158 ⩽ N ⩽ 218, 162 ⩽ N ⩽ 212 for Z = 122 and 128, respectively. The explicit density-dependent meson-exchange (DD-ME) and point-coupling (DD-PC) models within the framework of covariant density functional theory (CDFT) have been used to study the structural and decay properties of the isotopic series which includes the separable form of a finite range of pairing interaction. From the potential energy curves, the ground state properties of nuclei are predicted. Due to the importance of the shell effect in the superheavy region, the Strutinsky shell correction method has been employed for a better understanding of the extra stability of nuclei. The results from neutron pairing energy, two-neutron separation energy ( S 2 n ), single-particle energy levels, and total shell-correction energy strongly support N = 168, 174, and 178 as deformed neutron-magic numbers f...

在Z = 122、128个超重核的同位素序列中搜索中子魔术

对于Z = 122和128的区域，已分别在158⩽N 218、162⩽N 212区域系统地检查了超重核。在协变密度泛函理论（CDFT）的框架内使用显式密度依赖介子交换（DD-ME）和点耦合（DD-PC）模型来研究同位素序列的结构和衰变特性，其中包括有限范围的配对互动的可分离形式。从势能曲线可以预测原子核的基态性质。由于壳效应在超重区域中的重要性，因此采用Strutinsky壳校正方法可以更好地理解核的额外稳定性。结果来自中子配对能量，两个中子分离能量（S 2 n），单粒子能级，
