Measurement of the electrostrictive tensor of eight alkali halides

Abstract
The author presents the results of the measurements of the three independent electrostriction coefficients of LiF, NaF, NaCl, KCl, KBr, RbCl, RbBr and RbI. Measurements have been carried out with a double Michelson interferometer to ensure a high reliability. The values of the electrostriction coefficients presented here differ significantly from values reported earlier. The measured differences could be due to the use of an improved measurement set-up.
