Abstract
We present a novel method to identify energetic photons detected in a segmented electromagnetic calorimeter. It is based on topology analysi s of electromagnetic showers which develop in the detector following t he impact of photons. This approach supplements standard methods for t he most energetic photons detected in a given experiment and for which the limited statistics does not permit to define the parameters of th e pulse-shape analysis. The method is rested on photons with energies above E-gamma> 250 MeV produced in the reaction Ar+Ca at 180 AMeV and detected with the TAPS multidetector.
