Abstract
We have investigated the piezoreflectance spectra (Delta R/R) of the 1s Z(1 2) exciton in single crystals of copper bromide CuBr at the temperature of 95 K with linearly polarized light. The spectra were successively studied w ith the pressure p along the [001] and [111] axis and the wave vector k of the incident light parallel to the [1 (1) over bar 0] direction. The shear deformation potentials b and d of the 1s Z(12) exciton were deduced from th e stress-induced shift and splitting. The results are compared with those o btained in other works.
