论文摘要
N = Z核的带结构是由以四重奏定义的固有状态构建的。这些状态中最简单的是isospin t = 0的集体四重奏的冷凝物。其他固有状态是通过将冷凝物的一个四重奏提升为激发的T = 0配置来构建的。从这些固有状态，通过角动量投影，产生带状结构，可以很好地实验。投影状态还在很大程度上复制了基于形成内在状态的相同四重奏的配置相互作用计算所产生的光谱。这些结果表明，基于四重奏的固有状态提供了适当的框架，以简单而直观的方式理解n = z核中带状结构的出现。
The band structure of N=Z nuclei is constructed from intrinsic states defined in terms of quartets. The simplest of these states is a condensate of collective quartets with isospin T=0. The other intrinsic states are built by promoting one quartet of the condensate to an excited T=0 configuration. From these intrinsic states, by angular momentum projection, band structures are generated that approximate well the experimental ones. The projected states also reproduce to a very good extent the spectra resulting from configuration interaction calculations based on the same quartets forming the intrinsic states. These results show that the quartet-based intrinsic states provide the appropriate framework to understand in a simple and intuitive manner the emergence of band-like structures in N=Z nuclei.
