The first measurement of the temperature dependence of the muon transfer rate from muonic hydrogen to oxygen was performed by the FAMU collaboration in 2016. The results provide evidence that the transfer rate rises with the temperature in the range 104-300 K. This paper presents the results of the experiment done in 2018 to extend the measurements towards lower (70 K) and higher (336 K) temperatures. The 2018 results confirm the temperature dependence of ${\mathrm{\Lambda }}_{pO}$ observed in 2016 and sets firm ground for comparison with the theoretical predictions.

在70-336 K范围内测量从μ离子氢到氧的μ子转移速率

FAMU合作在2016年首次测量了μon离子从氢到氧的迁移率对温度的依赖性。结果表明，温度在104-300 K范围内，迁移率随温度升高而升高。在2018年完成的实验结果将测量范围扩展到了较低的温度（70 K）和较高的温度（336 K）。2018年的结果证实了温度的依赖性${\mathrm{\Lambda }}_{pØ}$ 于2016年观测到，为与理论预测的比较奠定了坚实的基础
