Abstract: | 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. |
