【 摘 要 】

In this work performed in frame to OLIMPIYA project [5] there are presented new results of measurement of fluxes and of the spectra of superheavy nuclei composing cosmic rays. The method of detection and analysis of nucleus tracks found in the olivine crystals of meteorites was used. The experiment is based on the combined method including the multistage meteorite etching and nucleus track registration and measurement on completely automated PAVICOM setup [5]. The track parameters such as diameter, length and the etching velocity are investigated. On the first stage of the experiment there was held the calibration procedure for nuclei charge identification using the accelerated nuclei Xe and U. The etching length of nuclei (26
