Проводится разделение ядер от водорода до бора включительно при помощи анализа распределений энерговыделений в плоскостях детекторов, обусловленных их флуктуациями. Также для каждого ядра на основе данных моделирования в Geant4 вычисляется оценка качества идентификации и вероятность ошибки (неверной идентификации).</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эксперимент PAMELA</kwd><kwd>космические лучи</kwd><kwd>идентификация частиц</kwd><kwd>кремниевые детекторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PAMELA experiment</kwd><kwd>cosmic rays</kwd><kwd>particle identification</kwd><kwd>silicon detectors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта №19-02-00951.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Picozza P., Galper A.M., Castellini G. et al. // Astropart.
