当带负电荷的介子在物质中停止时，它会被物质中的一个原子俘获，形成介子原子。Muon捕获过程受原子的化学环境和分子结构(化学效应)等因素的影响很大。在这项研究中，我们对低压CO、CO2和COS分子进行了Muon辐照，并测量了被原子俘获Muon后立即发出的Muon X射线。在本文中，我们利用LMM模型定量地讨论了每种原子的介子俘获几率。
When a negatively charged muon is stopped in a substance, it is captured by an atom of the substance, and the muonic atom is formed. The muon capture process is significantly affected by the chemical environment of the atom and factors such as molecular structure (chemical effect). In this study, we performed muon irradiation for low-pressure CO, CO2, and COS molecules and measured the muonic X-rays emitted immediately after muon capture by an atom. In this paper, we quantitatively discuss the muon capture probability of each type of atom using the LMM model.
