Popis:	We have calculated the stress-induced variations in refractive indices (of the index of refraction Δn and of the extinction coefficient Δk) of CuCl by the means of the Kramers–Kronig relationship from the piezoreflectance spectra of the 1s Z3 and 1s Z12 excitons. In the two studied configurations corresponding with the applied stress p //[001] and p //[111] the spectrum of the differential parameters Δk consist of two principals absorption lines in the region of the Z3 band. The corresponding energetic separation is comparable with the transverse-longitudinal splitting. The longitudinal Z3 exciton Γ5L is mixed with the transverse exciten Γ5T by virtue of the stress-induced k-linear term and became optically active.
