The FAMU experiment aims to measure for the first time the hyperfine splitting of the muonic hydrogen ground state. From this measurement the proton Zemach radius can be derived and this will shed light on the determination of the proton charge radius. In this paper, we describe the scientific goal, the method and the detailed preparatory work. This includes the outcome of preliminary measurements, subsequent refined simulations and the evaluation of the expected results. The experimental setup being built for the measurement of the hyperfine splitting to be performed at the RAL laboratory muon facility is also described.

FAMU实验:离子氢高精度光谱学研究

FAMU实验的目的是首次测量离子态氢基态的超精细分裂。通过该测量,可以得出质子的Zemach半径,这将为确定质子电荷半径提供启示。在本文中,我们描述了科学目标,方法和详细的准备工作。这包括初步测量的结果,后续精炼的模拟以及对预期结果的评估。还描述了为测量将在RAL实验室μon设备上进行的超细裂而建立的实验装置。
