Рассматривается возможность появления треков такой формы за счет электронов, проникающих в оливин на расстояние несколько микрометров от трека. Приводятся результаты расчетов, связанные с пространственно-временным развитием электронного ливня в процессе прохождения тяжелого иона через оливин. Показано, что объяснить наблюдаемый эффект только наличием δ-электронов не удается. Кроме того обсуждается соответствие ряда предположений некоторых моделей прохождения ионов через вещество полученным характеристикам δ-электронов.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>галактические ядра</kwd><kwd>метеориты</kwd><kwd>оливин</kwd><kwd>травление</kwd><kwd>GEANT4</kwd></kwd-group><kwd-group xml:lang="en"><kwd>galactic nuclei</kwd><kwd>meteorites</kwd><kwd>olivine</kwd><kwd>etching</kwd><kwd>GEANT4</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Alexeev V., Bagulya A., Chernyavsky M. et al. // Astrophys.
