我们报告的无核辛壳模型（NCSpM）的框架内，补充了无核壳模型（Navrátil，Vary和巴雷特）的最新进展，利用辛壳模型（Rowe和Rosensteel）的代数特征，同时也允许高性能的计算应用程序，但在高度截断，物理相关的子空间的完整空间。主要的辛对称性通常占低位态结构的70%到90%，这一结果仅适度依赖于所选核子间相互作用的细节。6Li，12 C，16 O，和20 Ne的例子被示出说明NCSpM的功效，以及与团簇和配对配置的强烈重叠，主导这些核中的低位态的动力学。
We report on recent developments within the framework of the no-core symplectic shell model (NCSpM) that complements the no-core shell model (Navrátil, Vary, and Barrett) by exploiting the algebraic features of the symplectic shell model (Rowe and Rosensteel) while also allowing for high-performance computing applications, but in highly truncated, physically relevant subspaces of the complete space. The leading symplectic symmetry typically accounts for 70% to 90% of the structure of the low-lying states, a result that is only moderately dependent on the details of the selected inter-nucleon interaction. Examples for6Li,12C,16O, and20Ne are shown to illustrate the efficacy the NCSpM, and as well the strong overlap with cluster-like and pairing configurations that dominate the dynamics of low-lying states in these nuclei.
