双幻核^(16)O附近核素^(14)C,^(14,15)N,^(14-18)O能谱结构的壳模型计算分析

Spectral Structure Analysis of Nuclei ^(14)C,^(14,15)N,^(14-18)O Near Double Magic Nucleus ^(16)O by Shell Model Calculations

根据YSOX,WBT以及WBP三种不同的有效相互作用对双幻核^(16)O附近同位素^(14)C,^(14,15)N,和^(14-18)O的能谱结构进行了比较分析,在结合相应的实验值的基础上揭示了重新考虑跨壳相互作用对壳模型理论计算的优化效果。借助不同的相互作用以及大量理论数据与实验值的对比,发现了已有壳模型有效相互作用在该核区的不足之处,例如部分能级误差较大、能级次序反转等,这为下一步改进这些有效相互作用创造了条件。

According to three different interactions of YSOX,WBT and WBP,the spectral structure of nuclei ^(14)C,^(14,15)N,and ^(14-18)O near double magic nucleus ^(16)O are analyzed by shell model calculations.The good effects have been found in spectral structure of these nuclei after reconsidering shell interaction.The large data analysis between these different shell model interactions and experiment also revealed the limitations of these existing interactions in this nuclei region,for example the large difference between theory and experiment,the reversed order of states and so on,which brings the further motivations of modifying shell model Hamiltonians.
