摘要
The Wilson-Curtis equation In(alpha (an)) = Int (alpha (0)(an)) - b/d(2) relating the anion polarizability alpha (an) to the anion-cation distances d in cubic NaCl-type alkali halides of the composition MX (M = Li, Na, K, Rb, Ca; X = F, Cl, Br, I) is found to be valid for the family MF2 and M1-xRxF2+x, crystals (M = Ca, Sr, Ba, Cd and R is a rare-earth metal) with the fluorite-type structure.
