Abstract
Potential retardation measurements with a variable-length drift tube have yielded the most probable energies of O+ ions in He, Ne and Ar buffer gases at 300K for selected values of reduced field E/n. For He, E/n was in the range 60-210 Td, for Ne, 80-510 Td and for Ar, 95-630 Td. The most probable energies obtained agree with the mean energies predicted by Wannier's equation for E/n>200 Td assuming ion drift velocities calculated from the polarisabilities; a comparison is also given.Keywords
