测量了母体气体、氦、氖和氩中原子和分子离子迁移率在 77-300 K 范围内的温度变化。将原子离子迁移率的实验值与基于荷斯坦理论的计算值进行了比较。氖气和氩气的结果与理论计算值非常一致。这与氦气的情况形成鲜明对比，氦气的实验结果始终低于理论值。将分子离子淌度与 Langevin 和 Hassé-Cook 理论预测的温度变化进行比较。氖气和氩气的实验结果介于两种理论的预测之间，与预期一致；然而，氦数据与这两种理论都不相符。
Measurements have been made of the temperature variation of the atomic and molecular ion mobilities in the parent gases, helium, neon, and argon over the range 77-300 K. The experimental values for the atomic ion mobilities are compared with calculations based on Holstein's theory. The results for neon and argon are in good agreement with the values calculated from the theory. This is in contrast to the case of helium where the experimental results lie consistently below the theoretical values. The molecular ion mobilities are compared with the temperature variation predicted by the Langevin and Hassé-Cook theories. The experimental results in neon and argon lie intermediate between the predictions of the two theories in agreement with expectations; however, the helium data cannot be reconciled with either of these theories.
