By studying fluctuations in the electrostatic potential of a single electrode immersed in a cold plasma, we were able to perform in situ electron spectroscopy. Electron exchange processes that occur at the surface of the electrode were triggered by the surface Auger process either using metastable molecular nitrogen or triplet helium at ambient conditions. Ongoing redox reactions were decomposed into their two fundamental half reactions and the reduction and oxidation potentials were detected. We found that redox reactions near the electrode surface are the result of binary interactions of a free electron gas with a free hole gas that occur on a femtosecond time scale. The measured lifetimes of electron-hole recombination processes and the elastic scattering rate of the hole-hole process are in fair agreement with theoretical estimates. The observed asymmetry in the energy distributions of free electron and free hole ensembles suggests that at thermal equilibrium the identity of hole differs from that of an electron vacancy.
