在 J-PARC（日本质子加速器研究中心）的 μ 子科学设施 (MUSE)，MuSEUM 合作计划正在计划在零场和高磁场下对 μ 子基态超精细结构 (HFS) 进行新的测量。之前的测量都是在 LAMPF（洛斯阿拉莫斯介子物理设施）进行的，实验不确定性主要由统计误差主导。 MUSE H-Line 即将推出的新型高强度 μ 介子束将为将这些测量的精度提高一个数量级提供机会。概述了这些新的锷 HFS 测量的不同方面、制备的现状以及零场首次调试测试实验的结果。
At the Muon Science Facility (MUSE) of J-PARC (Japan Proton Accelerator Research Complex), the MuSEUM collaboration is planing new measurements of the ground state hyperfine structure (HFS) of muonium both at zero field and at high magnetic field. The previous measurements were performed both at LAMPF (Los Alamos Meson Physics Facility) with experimental uncertainties mostly dominated by statistical errors. The new high intensity muon beam that will soon be available at MUSE H-Line will provide an opportunity to improve the precision of these measurements by one order of magnitude. An overview of the different aspects of these new muonium HFS measurements, the current status of the preparation, and the results of a first commissioning test experiment at zero field are presented.
