The nonequilibrium Auger transition is studied. The transition consists of a probe electron occupying a vacancy in the valence layer. The probe electron absorbs the energy released as a result of the valence electron transition into the K-layer followed by emission from the surface. The nonequilibrium Auger spectrum of electrons is obtained for the first time from the surface made of thin (8–10 atomic layers) Ag2O silver oxide films on a Si3N4 substrate for 8–10 keV probing radiation energy. The probability of escape for nonequilibrium Auger electrons is analyzed depending on the atomic number Z. The characteristic amplitude peaks are established. The peaks are consistent with the contribution of nonequilibrium Auger electrons to the signal recorded. A mathematical model describing the dynamics of the nonequilibrium Auger process is developed to estimate its probability, relaxation time, and the cross section of capturing a free charge carrier by a neutral vacancy.
