Our collaboration paper, “Improved Measurements of Muonic Helium Ground-State Hyperfine Structure at a Near-Zero Magnetic Field,” was published in Physical Review Letters 131, 253003.

DOI: 10.1103/PhysRevLett.131.253003

The experiment measured the ground-state hyperfine structure of muonic helium at near-zero magnetic field with substantially improved precision. Efficient formation of neutral muonic helium enabled a clean microwave-spectroscopy measurement and established a basis for further high-precision studies.

ミュオンヘリウム基底状態の超微細構造をほぼゼロ磁場で測定し、従来より大幅に精度を向上させた研究です。中性ミュオンヘリウムを効率よく生成することで明瞭なマイクロ波分光を実現し、さらに高精度な測定へ進むための基盤を確立しました。
