摘要

利用改进的裂变点模型计算和评价了汞同位素的裂变产率。在带有八极变形碎片的断裂点模型框架下，分析了180Hg的不对称裂变。180Hg的裂变质量不对称归因于N = 44,56和Z = 34,46壳隙对八极变形和液滴模型的影响。汞同位素非对称碎片中质子和中子数的演化也可以用八极形变壳隙来解释。

Influence of octupole deformed shell structure on the asymmetric fission of mercury isotopes

The fission yields of mercury isotopes were calculated and evaluated by using the improved scission point model. The asymmetric fission of ¹⁸⁰Hg was analyzed within the framework of the scission point model with octupole deformed fragments. The fission mass asymmetry of ¹⁸⁰Hg is attributed to the influence of N = 44, 56 and Z = 34, 46 shell gaps for octupole deformations and the liquid drop model. The evolution of proton and neutron numbers in asymmetric fragments of mercury isotopes is also explained by octupole deformed shell gaps.
