The results of the search for tracks of heavy and superheavy nuclei of galactic cosmic rays in the charge range Z = 26 − 129, identified in olivine crystals from Maryalahti and Eagle Station meteorites are presented. The database including characteristics of 21743 tracks, obtained in the OLIMPIA experiment, is currently the largest one within the charge range under study. It includes three tracks of superheavy nuclei with charge 119⁺¹⁰₋₆ and a minimum lifetime estimated as several tens of years, which can be considered as a direct experimental validation of the existence of natural superheavy nuclei from the “stability island”.

在自然界中发现超重核的电荷的确定

给出了在从Maryalahti和Eagle Station陨石的橄榄石晶体中发现的，在Z = 26-129电荷范围内的银河系宇宙射线重核和超重核的搜索结果。在OLIMPIA实验中获得的包括21743条磁道特征的数据库，目前是所研究电荷范围内最大的数据库。它包括电荷为119 ⁺¹⁰ _-6的三个超重核轨道，估计的最小寿命为几十年，这可以被视为对“稳定岛”中自然超重核存在的直接实验验证。
