摘要：
The results of the research in explosive decomposition of heavy metal azides initiated by electric ("streamer") charges induced by high-current electron beam have been considered. A physical model for initiation of heavy metal azides explosive decomposition by electron beam has been suggested. The model suggests formation of strong electric field in the sample and its neutralization by ultrasound anode charges. The streamer front generates "hot spots" which start the formation of explosive decomposition sites in a condensed reactive material. (C) 2010 Elsevier B.V. All rights reserved.
