摘要：

It is shown from the two-temperature theory of gaseous ion transport how the mobility of one isotope in a particular gas at fixed temperature can be obtained as a function of the ratio of electric field strength to the gas number density directly from mobility data of a different isotope of the same ion. This "aliasing" procedure is tested by comparing values calculated from the mobility of Ca-40(+) in He with those determined ab initio for a heavier, naturally-occurring isotope of Ca+. It is accurate enough that it obviates the necessity in future work of making calculations for more than one isotope.
