The constants of the empirical repulsion potential assumed by Born and Mayer between two ions, which may be termed the ionic ``radii,'' are calculated for the alkali and halide ions from the lattice constants of the alkali halides. By using 9 such radii the 20 lattice constants can be recalculated nearly within the probable experimental error of their determination. The good agreement is regarded as support for the assumptions involved in the calculations.
Huggins et al. (Fri,) studied this question.
