用LCR法观察到Mu自由基是μ原子作为溶质加入到丙烯酰胺中，浓度低至123.4 m时的产物。其最低浓度的产率与usr测得的~ 3 × 10~ 7 ~ ~ 3 × 10′6 s （PM= 0.20）之间的Mu产率密切对应。在高[AM]下，自由基产率（0.38）与Pu+ PL（和1-PD）非常吻合。水中所有的μ子都是这样的：62%的μ子“直接”转化为反磁性，其余的都以μ子原子的形式出现——其中大约一半从μ子轨道中逃脱。我们非常感谢与Bill Ng和Zhennan Wu的合作，以及John Worden和Keith Hoyle的协助。财政支持由加拿大国家科学研究委员会提供。
A Mu radical has been observed by the LCR method to be the product of a muonium atom adding to acrylamide as a solute at concentrations down to" 1 234 5M. Its yieldat the lowest concen-tration corresponds closely to the yield of Mu observed byuSR between~ 3 X 10~ 7 and~ 3 X 10" 6 s (PM= 0.20). At high [AM] the radical yield (0.38) corresponds very nicely to Pu+ PL (and to 1-PD). All the muons in water are thus accounted for: 62% of them are converted “directly” into diamagnetic states, andall the rest appear as muonium atoms—about half of which escape from the muon track.Acknowledgment. Collaborations with Bill Ng and Zhennan Wu and the assistance of John Worden and Keith Hoyle are much appreciated. Financial support was provided by NSERC of Canada.
