论文摘要
我们报告了旨在测量180 k <t <300 K的浓度氩气中O2离子的迁移率的结果。我们表明，通过使用热力学的自由体积（FV）模型来获得数据的足够理论描述，该模型最初是通过用于超级荧光素养的extruiled experlied explosing of of oe 2 of the Extimited of of of of of of of the of the of the of the of of of of ocy2的模型。模型目标是热力学预测可用于离子运动的可用空间。通过使用Millikan-Cunningham（MC）滑动校正因子实施FV模型，我们可以描述跨离子区域中的离子迁移率，将稀释的气体动力学桥接到离子运输的高密度流体动力状态。这些结果证实了模型的有效性及其某些特征的普遍性。
We report the results of the experiment aimed at measuring the mobility of O2- ions in dense argon gas in the temperature range 180 K < T < 300 K. We show that an adequate theoretical description of the data is obtained by using the thermodynamic Free Volume (FV) model, originally developed to describe the electron bubble mobility in superfluid helium and successfully exploited for describing the O2- mobility in near critical neon gas. The model goal is to thermodynamically predict the free space available for ion motion. By implementing the FV model with the Millikan-Cunningham (MC) slip correction factor, we can describe the ion mobility in the crossover region bridging the dilute gas kinetic regime to the high-density hydrodynamic regime of ion transport. These results confirm the validity of the model and the universality of some of its features.
