Abstract
Charged particles multiplicity distributions at the maximum of electromagnetic showers initiated by 5–1000 GeV electrons in Fe, W, and Pb were calculated using GEANT4. It is shown that they are well fitted by the inverse sum of two exponents and the energy dependence of the average multiplicity follows power law with the power of ~0.95 for all materials.
