Abstract: Electrons and positrons from <f>π0</f> decays have been measured for C+C collisions at <f>1 AGeV</f> beam energy. Reconstructed <f>e+e−</f>-pairs from <f>π0</f>-Dalitz decays have been used as a calibrated electron source for the investigation of Cherenkov rings detected in a hadron blind RICH with CsI-based photo cathode. The measured ring properties are in good agreement with full scale GEANT simulation calculations. [Copyright &y& Elsevier]
