The behavior of muons in water and ice is investigated by measuring spin rotation and relaxation of positive muons in water at 140–300 K, where we successfully observe oscillation in the zero-field spectra of muons in ice. The oscillation is attributed to the spin–dipole interactions between the muon in MuOH and neighboring protons and to hyperfine transitions of triplet states of axially symmetric anisotropic muonium in ice. The MuH distance in MuOH exceeds the H–H distance in H2O by 5% in ice.

通过μ子自旋旋转研究冰中MuOH的形成和结构



通过测量 140-300 K 水中正 μ 子的自旋旋转和弛豫来研究 μ 子在水和冰中的行为,我们成功地观察到了冰中 μ 子零场光谱的振荡。振荡归因于μ子之间的自旋偶极子相互作用 MuOH 和邻近的质子以及冰中轴对称各向异性锷三重态的超精细跃迁。这 MuH 距离在 MuOH 超过 H-H 距离 H2O 在冰中减少 5%。
