论文摘要
Z. Xu等。 [物理。 Rev. A 103，023114（2021）]报告了对增强因子$κ$的测量值，该测量表征了电子波函数与CS-$^{129} $ xe Spin-Exchange光学泵送（SEOP）的重叠的重叠，比以前的实验更高。这种差异没有合理的物理基础。由于作者反复误解了增强因素的性质和特性，并且没有完全描述其实验技术，因此在CS-XE SEOP及其应用的未来相关工作的背景下，没有理由接受或考虑这种结果。
Z. Xu, et al. [Phys. Rev. A 103, 023114 (2021)], have reported a measurement for the enhancement factor $κ$, which characterizes the overlap of the electron wavefunction with the noble-gas nucleus in Cs-$^{129}$Xe spin-exchange optical pumping (SEOP), that is more than an order of magnitude higher than previous experimental results and theoretical estimates. There is no plausible proposed physical basis for this discrepancy. As the authors repeatedly mischaracterize the nature and properties of the enhancement factor and do not completely describe their experimental technique, there is little reason to accept or consider this result in its current form in the context of future relevant work on Cs-Xe SEOP and its applications.
