A crossover effect between the dispersion curves of a charged vortex ring and an ion in liquid helium II is proposed with the hydrodynamic models of two intermediate states. This effect can satisfactorily explain various properties such as the field and pressure dependences of ion motions already reported by many researchers. The coupling energy Δ was estimated as 25 and 40 K for the positive and negative ions, respectively.
