负μ 鎓离子，μ/sup /减去μ/等于μ。mu../当一束正μ子穿过各种材料的薄箔时，通过双电子拾取器产生了sup +/e/sup/minus//e/sup /minus//。Mu/sup /minus//离子是通过在磁飞行时间谱仪中静电加速和分析离子来检测的。Mu/sup /minus//、Mu和.. mu../当..时，报告sup +/ as well。mu../ 380 - 800 keV动能的sup +/轰击薄Be、Al和Au箔。蒙特卡洛模拟提供了良好的协议与实验结果。
The negative muonium ion,Mu/sup /minus///equivalent to/..mu../sup +/e/sup /minus//e/sup /minus//, has been produced bydouble electron pickup as a beam of positive muons passes through thin foils ofvarious materials. The Mu/sup /minus// ions were detected byelectrostatically accelerating and analyzing the ions in a magnetictime-of-flight spectrometer. Yields of Mu/sup /minus//, Mu and..mu../sup +/ as well are reported when ..mu../sup +/ with kineticenergies from 380 to 800 keV impinge on thin Be, Al, and Au foils. A MonteCarlo simulation provides good agreement with the experimental results.
