โœฆ Synopsis

The theory of radiationless transitions is revised. At low temperatures, low energy gaps and finite concentrations of ions (impurities, defects, etc.), a usual assumption about equilibrium lattice phonons is not valid any more. For the concentrations of ions above certain characteristic concentrations, it is necessary to take into account the time dependence of phonon variables. Relaxation processes are described by coupled systems of equations for electronic and phonon variables. For specific models the characteristic concentrations are found.

In this Letter, non-equilibrium dissociation rates in expanding gas flows are studied taking into account state-tostate vibrational-chemical kinetics. A comparison of the results obtained in the state-to-state approach with the ones based on the quasi-stationary two-temperature vibrational distribut
