Background: The multiconfigurational dynamical symmetry (MUSY) is the common intersection of the shell, collective, and cluster models for the multi-major-shell problem. It is able to describe the spectra of different configurations in different energy windows in a unified way. It is based on some heuristic arguments, related to the connection of the wave functions, and energy eigenvalues. The detailed mathematical background has been worked out so far only for the simplest case of the two binary cluster configurations.

多构型动力学对称的微观结构和数学背景

背景：多构型动力学对称性 (MUSY) 是多主壳问题的壳、集体和集群模型的常见交集。它能够以统一的方式描述不同能量窗口中不同配置的光谱。它基于一些启发式论证，与波函数和能量特征值的连接有关。到目前为止，仅针对两个二进制集群配置的最简单情况制定了详细的数学背景。
