Abstract

The new method based on the classification algorithms was developed to separate antiprotons and electrons in the PAMELA experiment. Training samples based on Monte-Carlo simulation of particle's interactions in the PAMELA imaging Si/W calorimeter were used to achieve rejection factor and to keep high antiproton efficiency. With comparison to the previous publication the number of events was increased 1.5 times. Information collected from the mission start in 2006 till January 2010 was used in the analysis. 2800 events were found in the energy range from 60 MeV to 350 GeV. The flux of antiprotons in galactic cosmic radiation obtained with new method is presented.
