通过测量光电子在平行板电容器差距中的渡越时间，获得了纯净惰性气体和氮气中电子漂移速度的精确值。在纯氪和氙中的漂移速度以前还没有被测量过。对于其他气体所得到的值总是低于尼尔森报告的值，氖的差异很大。English和Hanna发现的氩在E {{p}_{0}} 10.1 $处的最大峰值，他们暂时认为是Ramsauer效应引起的，但在净化气体中没有观察到。
Accurate values of electron drift-velocity in purified noble gases and nitrogen have been obtained by measuring the transit time of photoelectrons across the gap of a parallel-plate condenser. Drift velocities in pure krypton and xenon have not been measured before. The values obtained for the other gases are invariably lower than those reported by Nielsen, the discrepancy for neon being large. The sharp maximum found by English and Hanna for argon at $\frac{E}{{p}_{0}}l0.1$ and tentatively ascribed by them to the Ramsauer effect was not observed in the purified gas.
