Muons implanted into ionic fluorides often lead to a so-called F– μ –F state, in which the time evolution of the muon spin contains information about the geometry and nature of the muon site. Nuclei more distant from the muon than the two nearest-nei... Read More about Muon sites in PbF2 and YF3: Decohering environments and the role of anion Frenkel defects.
