摘要:

我们应用库仑和邻近势模型CPPM计算了所选核的偶偶同位素的各种团簇衰变的半衰期。这些原子核是周期表中的第5d过渡金属区域中的Hf、W、Os、Pt和Hg,其中原子序数72大于或等于Z小于或等于80。此外,半衰期计算使用的通用公式簇衰变。所选同位素的α衰变半衰期的计算值与实验数据,特别是与CPPM的结果符合得很好。α衰变和簇衰变更可能来自较重的质量数A等于168,180的母体,而不是较轻的质量数A等于156,166的母体。

英文摘要:

We have applied the Coulomb and proximity potential model,CPPM to calculate the half lives for various clusters decay of the selected even-even isotopes of the chosen nuclei. These nuclei are Hf, W, Os, Pt, and Hg in the 5d transition metal region in the periodic table with atomic number 72 greater or equal Z less than or equal 80. Furthermore, the half-lives are calculated using the universal formula for cluster decay. The calculated half-lives of alpha decay for the chosen isotopes are in good agreement with the experimental data, especially with the CPPM results. The alpha and cluster decays are more probable from the parents in the heavier mass number A equal 168,180 than from the parents in the lighter mass number A equal 156, 166.
