摘要：
Mobilities of OH+ and OD+ ions in cooled helium gas have been measured at gas temperature of 4.3 K. Measured mobilities of both ions as a function of an effective temperature T-eff show a minimum around 80 K, and they are approaching to the polarization limits at very low T-eff. These findings will be related to the extremely strong anisotropy of the interaction potential between the molecular ion and helium atom.
