The kinetics of the predetonation conductivity of silver azide have been me
asured with nanosecond time resolution. The experimental results are accura
tely approximated by an equation which includes multiplication of active pa
rticles by a first-order reaction and loss of these particles by a second-o
rder reaction. (C) 1999 American Institute of Physics. [S1063-7850(99)02311
