Part of the Lecture Notes in Physics book series (LNP, volume 57)


Splittings of spontaneous emission lines in laser excited wurtzitetype CdS and ZnO are observed under a uniaxial stress at 1.8 K. The relative intensity of the split components of the excitonic molecule emission line is accounted for by using Hanamura's wave function for the excitonic molecule.
