Effect of Temperature on the Growth Rate of Pre-Explosion Luminescence in Silver Azide

摘要

The effect of temperature on the growth rate of pre-explosion luminescence in crystals is examined.It is found in experiments that the reaction rate of the explosive decomposition at 300 K is higher than at 80 K.It can be inferred from here that the limiting stage for the chain reaction is electron capture on a neutral center (diva-cancy).The data obtained agree well,both qualitatively and quantitatively,with the previously reported model of initiation in heavy metal azides,thus providing support to the divacancy model.
