Abstract
The article presents a method for identifying light nuclei in cosmic rays from PAMELA spectrometer measurements of magnetic rigidity and energy losses of particles along the track in the time-of-flight and tracking systems. Nuclei from hydrogen to boron inclusive are separated by analyzing energy loss distributions in detector planes caused by their fluctuations. The identification quality estimate and the error (misidentification) probability are also calculated for each nucleus on the basis of Geant4 simulation data.
