基于β稳定线和α衰变能对液滴模型和原子核球堆积模型的比较研究

摘要

采用原子核球堆积模型及液滴模型两种核结构模型的核素结合能解析式及推导公式,选取β稳定线上90种核素和具有α衰变能的152种核素进行模型分析.结果表明:在核素β稳定线解析方面,原子核球堆积模型比液滴模型能更好地解释β稳定线质子数Z与核质量数A之间的关系;但从α衰变能角度分析,液滴模型却比原子核堆积模型更适合.%We used nuclear binding energy analytical formulas based on two nuclear structure models respectively (liquid drop model and nuclear sphere packing model),and selected 90 nuclides on the β-stability line and 152 nuclides which have α-decay capability for model analysis.The results show that:for β-stability line analysis,nuclear sphere packing model can better explain the relationship between proton number Z and atomic mass A than liquid drop model,while liquid drop model works better on α decay energy analysis.
