Abstract
We have observed a narrowing of the luminescence line from excitons in germanium with the application of a uniaxial stress along the [111] crystallographic axis. In zero stress the line is broadened by the two split excitons and the mass-reversal effect, while at our stress of 15 kg mm2 only one band is occupied. We find that the high stress density of states varies nearly as the square root of energy.
