Abstract
The elastic constants of KCl and NaCl have been determined by studying Brillouin scattering at 90°. The scattered light was analysed by a pressure scanned Fabry-Perot interferometer, the pressure in which was monitored by a Michelson interferometer. Our results have an accuracy comparable to the results of recent ultrasonic measurements, and the agreement between the two methods is excellent in most cases. It is believed that the accuracy of the method described here could be substantially increased by further refinements of the experimental apparatus.Keywords
