Charge composition of the VVH cosmic ray nuclei in the energy range of 1-2 GeVucleon: The results of the track investigation in olivine from the Marjalahti pallasite

摘要

New results of the measurements performed in the "OLIMPIA" project framework of the relative abundance of superheavy (Z >= 50) nuclei in galactic cosmic rays are presented. The method of detection and analysis of nucleus tracks in olivine crystals from the Marjalahti pallasite was based on the combination of the multistage etching of individual crystals and measurement of the track parameters (etchable length and corresponding track-etching rate) on the completely automated PAVICOM setup.
