We report the results on the lateral distribution of electrons in elec
tromagnetic air showers generated by 10 divided by 10(9) GeV photons i
n a wide range of distances from the shower core. We demonstrate a new
scaling property and give a parametrization of the invariate part of
the electron lateral distribution which enable to solve the problems o
f the design studies of new large air-shower arrays and interpretation
of the observational data.
