论文摘要
我们基于核子核子的现实相互作用,基于其SU(3)分解对SU(3) - 对称成分。我们发现,这些相互作用组件中的许多都可以忽略不计,这反过来又使我们能够识别一部分物理相关的组件,这些组件足以描述$^{12} $ c和相关可观察到的低洼状态的结构,例如激发能量,例如电力四倍体转移和RMS radii。我们发现,将相互作用削减到SU(3) - 对称成分或更多产率结果的一半,这些结果实际上与相应的从头算计算与完整相互作用相吻合。此外,我们表明,尽管各种现实的相互作用在SU分解(3)分解中有所不同,但其重新归一化的有效对应物表现出惊人的相似性和组成,这些相似性和组成可能与主导核特征(例如变形,配对,聚类和自旋轨道效应)相关。
We examine nucleon-nucleon realistic interactions, based on their SU(3) decomposition to SU(3)-symmetric components. We find that many of these interaction components are negligible, which, in turn, allows us to identify a subset of physically relevant components that are sufficient to describe the structure of low-lying states in $^{12}$C and related observables, such as excitation energies, electric quadrupole transitions and rms radii. We find that paring the interaction down to half of the SU(3)-symmetric components or more yields results that practically coincide with the corresponding ab initio calculations with the full interaction. In addition, we show that while various realistic interactions differ in their SU(3) decomposition, their renormalized effective counterparts exhibit a striking similarity and composition that can be linked to dominant nuclear features such as deformation, pairing, clustering, and spin-orbit effect.
