摘要：

Hot photoluminescence spectra (HPL) of uniaxially stressed GaAs are investigated. From the stress-induced shift and splitting in the HPL spectra, shear deformation potentials for the subsidiary minima have been determined with a good accuracy. From the stress dependence of the relative intensities in the split spectrum a value of the coupling constant for scattering between the L-valleys is obtained as D//L//L equals (5 plus or minus 1) multiplied by 10**8 ev cm** minus **1.
