基于使用纯氢操作的时间投影电离室，在一系列实验中研究了温度范围为 28 至 350 K 的 D-2 和 HD 气体中 μ 介子催化的 dd 聚变。该反应链中的所有主要观测值均以高绝对精度测量，包括共振和非共振 dd mu 形成速率、d mu 原子超精细跃迁速率、两个电荷对称聚变通道 He-3 + n 和 t + p 的分支比以及 μ 子粘着概率。该报告介绍了数据的最终分析以及与基于最新 mu CF 理论的计算的全面比较。量子数 J = 1、nu = 1 的松散束缚 dd mu 态的能量是共振分子形成机制的核心，可精确提取 E >(11)(fit) = -1.9651(7) eV。与最新理论结果 E >(11)(理论) = -1.9646 eV 令人印象深刻的一致。
Muon catalyzed dd fusion in D-2 and HD gases in the temperature range from 28 to 350 K was investigated in a series of experiments based on a time-projection ionization chamber operating with pure hydrogen. All main observables in this reaction chain were measured with high absolute precision including the resonant and non-resonant dd mu formation rates, the rate for hyperfine transitions in d mu atoms, the branching ratio of the two charge symmetric fusion channels He-3 + n and t + p and the muon sticking probability. The report presents the final analysis of the data together with a comprehensive comparison with calculations based on recent mu CF theories. The energy of the loosely bound dd mu state with quantum numbers J = 1, nu = 1, which is central to the mechanism of resonant molecule formation, is extracted with precision E >(11)(fit) = -1.9651(7) eV. in impressive agreement with the latest theoretical results E >(11)(theory) = -1.9646 eV.
