Abstract
In this study, we investigate etched channels of a special shape that arise during the search for superheavy nuclei in olivines from meteorites. The possibility of the appearance of tracks of this shape due to electrons penetrating olivine at a distance of several microns from the track is considered. The calculation results related to the spatio-temporal development of an electron shower during the passage of a heavy ion through olivine are presented. It has been shown that it is not possible to explain the observed effect only by the presence of δ electrons. In addition, the correspondence of a number of assumptions of some models of ion passage through matter to the obtained characteristics of δ electrons is discussed.
