标题： Ab initio study of Z(N) = 6 magicity

摘要： 原子核内质子和中子的幻数的存在对于理解核结构和基本核力至关重要。几十年来，研究人员针对新幻数 Z(N)=6 展开理论和实验研究，关注半径、结合能、电磁跃迁和核子分离能等可观测量。我们对 Z(N)=6 和 Z(N)=8 同位素（同位素）基态中最低单粒子态的占据数进行了从头算无核壳模型计算。我们的计算结果并不支持 Z(N)=6 在一系列原子序数范围内作为一个幻数。然而，14C 和 14O 显示出双幻数核的特征。 显示英文摘要

摘要： The existence of magic numbers of protons and neutrons in nuclei is essential for understanding nuclear structure and fundamental nuclear forces. Over decades, researchers have conducted theoretical and experimental studies on the new magic number Z(N) = 6, focusing on observables such as radii, binding energy, electromagnetic transition, and nucleon separation energies. We perform the ab initio no-core shell model calculations for the occupation numbers of the lowest single particle states in the ground states of Z(N) = 6 and Z(N) = 8 isotopes (isotones). Our calculations do not support Z(N) = 6 as a magic number over a span of atomic numbers. However, 14C and 14O exhibit the characteristics of double-magic nuclei.
