Abstract

Measurements of muon-catalyzed dt fusion ( d(mu)t-->4He + n + mu(-)) in solid HD have been performed. The theory describing the energy dependent resonant molecular formation rate for the reaction (mu)t + HD-->(d(mu)t)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 microg x cm(-2) targets, an average formation rate consistent with 0.897+/-(0.046)(stat)+/-(0.166)(syst) times the theoretical prediction was obtained.

摘要

已对固体HD中μ子催化的dt聚变（d（μ）t→4He + n +μ-）进行了测量。将描述反应（μ）t + HD→[（d（μ）t）pee]*能量依赖的共振分子形成速率的理论与纯固体HD靶中的实验结果进行了比较。通过使用专门为该实验开发的蒙特卡罗模型推断出速率的约束条件。从对16和37μg x cm-2靶中聚变事件的飞行时间分析中，获得了与理论预测的0.897±（0.046）（统计）±（0.166）（系统）倍一致的平均形成速率。
