AI 中文摘要
我们研究了玻尔 - 索末菲量子化条件和冲击频率对α衰变半衰期在半经典模型中的影响。利用双折叠模型,通过具有有限范围交换项的CDM3Y3密度依赖核子 - 核子相互作用计算α粒子与子核之间的势。结果表明,玻尔 - 索末菲条件的恰当应用会使特定势形式下计算出的α衰变半衰期有显著变化。我们还基于广义振子势对冲击频率提出了一种替代处理方法。这种对冲击频率的描述显著改善了计算的α衰变半衰期与实验数据之间的一致性。
英文摘要
We study the impacts of the Bohr-Sommerfeld quantization condition and the assault frequency on the α decay half-life within the semiclassical model. The potential between the α particle and daughter nucleus is calculated by the double-folding model using the CDM3Y3 density-dependent nucleon-nucleon interaction with a finite-range exchange term. We show that the proper implementation of the Bohr-Sommerfeld condition leads to a considerable change of the calculated α decay half-life with certain forms of potential. We also propose an alternative treatment for the assault frequency based on the generalized oscillator potential. This description of assault frequency considerably improves the agreement between the calculated α decay half-lives and the experimental data.
