由静态晶体极化率得到了碱金属、碱土金属和卤化物离子自由离子极化率的经验值。结晶环境显著降低了阴离子的极化率，但折射率数据不支持阳离子极化率的显著扰动。阳离子的结果与先前的结论相矛盾，但与最近的实验和理论工作是一致的。得到的经验极化率分别为：K+=0.85±0.02；Rb+，1.41±0.02；Cs+，2.42±0.03；Ba2+，1.73±0.05；F“，1.38±0.1；Cl2+，3.94±0.2；Br2+，5.22±0.2；I-，‘7.8 L’±0.3A3。
Empirical values for the free-ion polarizabilities of alkali metal, alkaline earth metal, and halide ions have been obtained from static crystal polarizabilities. The crystalline environment significantly reduces the po-larizabilities of the anions, but the refractive index data do notsupport a significant perturbation of the cation polarizabilities. The result for the cations contradicts earlier conclusions, but is in agreement with recent experimental and theoretical work. The empirical polarizabilities obtained were: K+= 0.85±0.02; Rb+, 1.41±0.02; Cs+, 2.42±0.03; Ba2+, 1.73±0.05; F", 1.38±0.1; Cl~, 3.94±0.2; Br~, 5.22±0.2; I-,'7.8 l ‘±0.3 A3.
