Abstract

An extended group function model has been applied to determine the interatomic potential for the X ¹Σ state of HeLi⁺, to an accuracy superior to previously determined potentials. The potential has been used to calculate transport coefficients for Li⁺ ions in He at 77.5 and 295 K. and new precision measurements of the mobility as a function of E/N have been performed at these temperatures. The agreement between the theoretical and experimental mobility values is excellent, and well within the experimental scatter.
