Firm evidence for a radio emission counterpart of cosmic ray air showers is presented. By the use of an antenna array set up in coincidence with ground particle detectors, we find a collection of events for which both time and arrival direction coincidences between particle and radio signals are observed. The counting rate corresponds to shower energies \gtrsim 5× 1016 eV. These results open overwhelming perspectives to complete existing detection methods for the observation of ultra high-energy cosmic rays.
