Abstract
A set of electronic polarizabilities has been obtained from a least-squares fit of experimental refraction data using simple additivity and a Lorentz factor of . Except for the fluorides, the electronic polarizability values of the alkali-halide crystals calculated from this set agree with the experimental data within 3 percent. Similar least-squares fits were attempted with various values of the Lorentz factor, the best fit being obtained for . On the basis of , the additivity assumption and the alkali-halide set, polarizabilities have been obtained for other ions. The best values for the sodium line in are 0.03, 0.41, 1.33, 1.98, 3.34, 0.64, 2.96, 4.16, 6.43, 1.1, 1.6, 2.5, 0.5-3.2, 4.8-5.9, 6.0-7.5, 8.3-10.2, 2.4, 1.6, 0.2, 0.8, 1.8, 1, 3.4, 4.9. Values represented by a spread indicate ions that cannot be treated additively.
