固体HD中共振$dμt$分子生成速率的测定
Measurement of the Resonant $dμt$ Molecular Formation Rate in Solid HD
摘要:
测量了固体HD中μ子催化的dt融合($dμt \to ^4He+n+μ^-$)。的理论描述的能量依赖的共振分子形成率的反应$μt$ + HD $\to [(dμt)pee]^*$相比,在一个纯固体HD目标的实验结果。通过使用专门为实验开发的Monte Carlo模型来推断对速率的限制。通过对16个和37个$μg\cdot cm^{-2}$靶的融合事件的飞行时间分析,得到了与理论预测的0.897倍的$\pm$(0.046)$_{stat}\pm$(0.166)$_{syst}$一致的平均形成率。
英文摘要:
Measurements of muon-catalyzed dt fusion ($dμt \to ^4He+n+μ^-$) in solid HD have been performed. The theory describing the energy dependent resonant molecular formation rate for the reaction $μt$ + HD $\to [(dμt)pee]^*$ is compared to experimental results in a pure solid HD target. Constraints on the rates are inferred through the use of a Monte Carlo model developed specifically for the experiment. From the time-of- flight analysis of fusion events in 16 and 37 $μg\cdot cm^{-2}$ targets, an average formation rate consistent with 0.897$\pm$(0.046)$_{stat}\pm$ (0.166)$_{syst}$ times the theoretical prediction was obtained.
