本文给出了$\ensuremath{\mu}d$和$\ensuremath{\mu}t$原子在冷却到$3\phantom{\rule{0.3em}{0 ex}}\mathrm{K}$的固体氢中散射的实验研究结果。在TRIUMF实验E742中观察到了拉姆绍尔-汤森效应产生的强烈效应，其中μ子被阻止在薄的冻结氢层中。测量的Ramsauer-Townsend最小能量$\ensuremath{\mu}d$和$\ensuremath{\mu}t$原子和最小截面与理论一致。
We present the final results of an experimental study of $\ensuremath{\mu}d$ and $\ensuremath{\mu}t$ atom scattering in solid hydrogen cooled to $3\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. Strong effects resulting from the Ramsauer-Townsend effect have been observed in the TRIUMF experiment E742 where muons were stopped in thin frozen layers of hydrogen. The measured Ramsauer-Townsend minimum energy for both $\ensuremath{\mu}d$ and $\ensuremath{\mu}t$ atoms and the minimum cross section are in agreement with theory.
