Shell evolution in nuclei investigated with large-scale shell-model calculations

我们利用基于壳模型的大尺度核结构计算，对阐明导致不稳定核壳结构演化的机制做出了巨大贡献。特别是，我们已经建立了一个框架，描述了不稳定核的结构周围的中子数，表示为N，28，并提出了一个新的图片命名为“张量力驱动的Jahn-Teller效应”来解释的起源N=28幻数的消失。此外，我们还揭示了N=28以上不稳定核的壳层结构。我们还大大提高了蒙特卡罗壳模型方法，使非常大规模的壳模型计算。

We have made a large contribution to clarifying the mechanism that causes the evolution of shell structure in unstable nuclei, using large-scale nuclear-structure calculations based on the shell model. In particular, we have constructed a framework that describes the structure of unstable nuclei around neutron number, denoted N, 28, and proposed a new picture named “tensor-force driven Jahn-Teller effect” to account for the origin of the disappearance of the N=28 magic number. Furthermore, we have revealed the shell structure of unstable nuclei beyond N=28. We have also greatly advanced the Monte Carlo shell-model method to enable very large-scale shell-model calculations.
