摘要:

最近的PSI兰姆位移实验和关于质子大小的争论重新引起了人们对测量μ子氢超精细分裂的兴趣,作为比较质子电磁结构的普通和μ子氢光谱数据的另一种可能性。这种测量关键取决于超热范围内μ介子向较重气体转移速率的能量依赖性。现有数据仅提供定性信息,理论预测尚未得到验证。本文提出了一种新的方法,通过测量不同温度下热化靶中的转移率,估计了其精度,并探讨了最佳实验条件。

英文摘要:

The recent PSI Lamb shift experiment and the controversy about proton size revived the interest in measuring the hyperfine splitting in muonic hydrogen as an alternative possibility for comparing ordinary and muonic hydrogen spectroscopy data on proton electromagnetic structure. This measurement critically depends on the energy dependence of the muon transfer rate to heavier gases in the epithermal range. The available data provide only qualitative information, and the theoretical predictions have not been verified. We propose a new method by measurements of the transfer rate in thermalized target at different temperatures, estimate its accuracy and investigate the optimal experimental conditions.
