在无核壳模型框架下碳-12的Hoyle态和转动特征
Hoyle state and rotational features in Carbon-12 within a no-core shell model framework
摘要:
通过仅使用一小部分的模型空间扩展到目前的无芯壳模型的限制和示意性的有效多核子相互作用,我们获得了额外的洞察力在一个多体引导壳模型框架内,到多体动力学,引起的基态旋转带连同现象联系在一起的α-集群子结构在低的状态在C-12,特别是,具有挑战性的霍伊尔态和它的第一个2+激发。对于这些国家,我们提供了一个新的视角出现的无核壳模型的考虑,包括相关的核形状和物质半径的讨论。这反过来又为从头算壳模型提供了指导,告知原子核结构的关键特征和相互作用。
英文摘要:
By using only a fraction of the model space extended beyond current no-core shell-model limits and a schematic effective many-nucleon interaction, we gain additional insight within a symmetry-guided shell-model framework, into the many-body dynamics that gives rise to the ground state rotational band together with phenomena tied to alpha-clustering substructures in the low-lying states in C-12, and in particular, the challenging Hoyle state and its first 2+ excitation. For these states, we offer a novel perspective emerging out of no-core shell-model considerations, including a discussion of associated nuclear shapes and matter radii. This, in turn, provides guidance for ab initio shell models by informing key features of nuclear structure and the interaction.
