Using an EPM‐ k · p method the K and L emission bands in AlSb and GaP have been calculated based on the corresponding band structures. The results are in good agreement with experimental data in particular for the K bands. For the L bands there is a larger sensitivity with regard to the quality of the valence‐band wave‐functions used. Due to the influence of the transition probability marked differences between the spectra of the A and B components both for K and L emission are obtained. The antisymmetric form factors of the pseudopotential influence the value of the antisymmetric gap such that they may be tested or corrected with the help of X‐ray spectra.
