Abstract
New analysis to separate electrons from protons in the ATIC experiment has been performed. Five new discriminants were studied by different Monte Carlo programs. New electron spectrum, when compared with the published results [1], show good agreement inthe most interesting region of energy (from 90 GeV to 600 GeV). It is argued that there is no disagreement between ATIC's results and Fermi-LAT ones. Finally, high-resolution electron spectrum is obtained and possible fine structure is found out in it.
