原子和分子氦离子的迁移率是用类似于Biondi和Chanin描述的装置测量的，但进行了一些修改。在296 °K时，原子离子的迁移率μ0（He+）= 10.6 ± 0.15cm ~ 2/Vs，两种分子离子的迁移率μ0（He ~（2+））= 16.0 ± 0.28cm ~ 2/Vs，μ0（He ~（2+））= 20.4 ± 0.26cm ~ 2/Vs。 在195 ~ 665 °K温度范围内测量了这三种迁移率。原子离子的迁移率随温度的升高而降低，而分子离子的迁移率随温度的升高而升高。测量结果与文献中的理论计算结果进行了比较。
The mobilities of atomic and molecular helium ions were measured with an apparatus similar to that described by Biondi and Chanin, but with some modifications. Three species of ions were found. For the mobility of atomic ions a value of μ0(He+) = 10.6 ± 0.15 cm2/V s, for that of the two species of molecular ions μ0(He2+) = 16.0 ± 0.28 cm2/V s, and μ0(He2+) = 20.4 ± 0.26 cm2/V s have been obtained at 296 °K. The three kinds of mobilities have been measured in the temperature range from 195 to 665 °K. The mobility of the atomic ions decreased with the rise of temperature, while the mobilities of both molecular ions increased. The measurement results have been compared with those of theoretical calculations found in the literature.
