摘要:

本文简要评述了偶偶超重核裂变势垒和裂变半衰期的计算方法和结果。本文讨论了以下方法的一致性:基于对液滴模型进行壳修正的宏观-微观方法,以及基于Hartree-Fock-Bogoliubov方法自洽计算Skyrme和Gogny型微观能量密度泛函的方法。在Hartree-Fock-Bogoliubov曲柄近似中计算质量参数。本文的一小部分是关于核裂变动力学的。我们还讨论了Skyrme泛函应用于$^{266}$ Hs裂变路径的关键属性的预测能力。它适用于标准技术的误差估计的框架内的$χ^2$分析。

英文摘要:

This is a short review of methods and results of calculations of fission barriers and fission half-lives of even-even superheavy nuclei. An approvable agreement of the following approaches is shown and discussed: The macroscopic-microscopic approach based on the stratagem of the shell correction to the liquid drop model and a vantage point of microscopic energy density functionals of Skyrme and Gogny type selfconsistently calculated within Hartree-Fock-Bogoliubov method. Mass parameters are calculated in the Hartree-Fock-Bogoliubov cranking approximation. A short part of the paper is devoted to the nuclear fission dynamics. We also discuss the predictive power of Skyrme functionals applied to key properties of the fission path of $^{266}$Hs. It applies the standard techniques of error estimates in the framework of a $χ^2$ analysis.
