Uniaxial‐stress‐induced shift and deformation of the plasma edge has been observed in polarized light for single crystals of LaB 6 , PrB 6 , NdB 6 , and CeB 6 . Stress modulation technique was used. It is shown, that the shift and deformation of the plasma edge is due to the change of the parameters which determine the reflectivity in this region, i.e. free electron concentration, effective mass, relaxation time, and lattice dielectric constant. The change of the parameters was estimated and the shift of the plasma edge determined, using experimental results for all investigated compounds.
