We take macroscopic (x‐ray attenuation) and microscopic (Mössbauer line broadening) measurements of ions diffusing in a cold liquid. Combined, the results demonstrate that jumps the size of lattice dimensions do not take place, in contrast to crystalline diffusion. Surprisingly from molecular dynamical considerations, D is Arrhenius‐like over four decades.
