Abstract
To separate the particles such as electrons and positrons, which are insignificant in number, from the total particle flux of cosmic rays, reliable enough criteria of their selection should be found. The proposed selection technique based on such criteria as the interaction in the first calorimeter layers, difference in the energy release for protons and electrons, and the measured number of neutrons makes it possible to separate electrons from the total charged particle flux with an impurity fraction no larger than 2% of the electron flux.
