Measurements of repulsive interactions of closed-shell alkali and halogen ions with He and Ne atoms by ion-beam scattering are compared with measurements of ion mobility and diffusion in drift tubes at high electric field strengths. Both measurements probe the repulsive interaction and have a region of overlap which can be tested for consistency. As a by-product, generalized Einstein relations for calculating ion diffusion coefficients from measured mobilities are also tested. The overall agreement is good, and the few discrepancies are discussed. Their probable causes can be assigned with some confidence because of the high redundancy in the data.
