Abstract

In this paper, we present the last results of the OLIMPIA experiment on the search for and study of traces of heavy and superheavy element nuclei of galactic cosmic rays in olivine crystals from meteorites. The charge spectrum of cosmic rays in the region of heavy nuclei is obtained, three superheavy nuclei of natural origin with charges in the range 105 < Z < 130 and lifetimes longer than 3000 years, being a part of the so-called “stability island”, are identified.
