Description

Positron lifetime spectra were recorded and evaluated in mixtures of Zn + S and Zn + Se ground for various periods. The intensity of the long-lived positron lifetime component is shown to increase with grinding time until a sudden decrease taken place at a specific grinding time thereby indicating the onset of the effective chemical reaction. The suitability of positron annihilation for investigating mechanochemical reactions is clearly demonstrated. (orig.)
