Abstract

Investigation of the interaction of muons with complex nuclei yields important results on the properties of nuclei and on their electromagnetic interaction with muons happening to be in the Coulomb field of the nucleus. The muon serves as a unique instrument in studies of the charge distribution and of other properties of nuclei. The following are processes which yield information relevant to the properties of nuclei. This work is the first (and unique) investigation of the dynamic E0 excitation of nucleus at µ^– decay on the K-orbit of muonic atom. This excitation mechanism permits one to get per se nuclear monopole excitation. Study of nuclear excitation by the bound muon is of independent interest— the discovery of a new process and validation of ideas about it in the future can provide a new complementary method for studying nuclear monopole states. Information on the phenomenon investigated in the present work is of interest from the point of view of analysis of neutrinoless µ → ẹ conversion in Mu2e and COMET experiments.

152 Sm的介子静止引起的核伽马辐射

摘要

对μ子与复杂原子核之间相互作用的研究，对原子核的性质以及它们与恰好发生在原子核库伦场中的μ子的电磁相互作用产生了重要的结果。介子是研究电荷分布和原子核其他性质的独特工具。以下是产生与核性质有关的信息的过程。这项工作是在μ核的动态E0激励的第一个（也是唯一的）调查^-在电子原子的K轨道上衰变。这种激发机制允许人们获得核单极激发。束缚介子对核激发的研究具有独立的意义-将来发现新过程并验证其想法可为研究核单极子态提供新的补充方法。从分析Mu2e和COMET实验中无中微子μ→ẹ转换的角度来看，有关当前工作中研究的现象的信息是令人感兴趣的。
