Effects of the condensation and scattering of radiation at the plasma-dynamic expansion of the detonation products of lead azide

The kinetics of the superluminescence of lead atoms, $\mathrm{Pb}$ ${}^3P_1^0\to {}^1D_2$ ($722.9$ nm) and ${}^3P_1^0\to {}^3P_2$ ($405.8$ nm), at the fast adiabatic expansion and cooling of the detonation products of lead azide $\mathrm{Pb}(\mathrm{N}_3)_2$ in vacuum has been studied. The effects of the condensation and scattering of light from drop clusters in an optically active heterophase medium has been analyzed in order to interpret the experiments in laser detonation plasma-dynamic systems based on metal azides.
