Abstract
The description of identification method of high energy electrons with the calorimeter of PAMELA satellite experiment is presented. The method provides selection and energy measurement of electrons and positrons in energy range from tens of GeV up to one TeV. Developing of this method is necessary for energy range above 300 GeV where measurements by magnetic spectrometer are impossible. This energy region is of particular interest as positron-electron spectrum above 100 GeV can have signatures from cosmological processes like dark matter particles annihilation or generation in the near-by pulsar magnetospheres. Preliminary spectrum obtained shows a quite good agreement with data of other experiments.
