用于研究物质结构的μ子自旋旋转/弛豫/共振（MuSR）技术是通过最近引入的量子自旋态的概率表示来考虑的。建立了实验 MuSR 直方图和 μ 子自旋断层图之间的关系。在断层扫描表征中研究了μ、反常μ和类μ系统的时间演化。鉴于贝尔数和正部分转置（PPT）准则的断层扫描类似物，研究了二分μ子电子系统的纠缠现象。讨论了μ子-电子自旋态的重建以及组成系统的总自旋断层扫描。
The muon spin rotation/relaxation/resonance (MuSR) technique for studying matter structures is considered by means of a recently introduced probability representation of quantum spin states. A relation between experimental MuSR histograms and muon spin tomograms is established. The time evolution of muonium, anomalous muonium, and a muonium-like system is studied in the tomographic representation. The entanglement phenomenon of a bipartite muon–electron system is investigated, in view of the tomographic analogs of the Bell number and the positive partial transpose (PPT) criterion. Reconstruction of the muon–electron spin state as well as the total spin tomography of the composed system is discussed.
