Распады 8Be идентифицируются в широком диапазоне энергий по инвариантным массам, вычисляемым по углам разлета в 2α-парах. Принятые приближения проверены по данным фрагментации ядер 16О в водородной пузырьковой камере в магнитное поле. Обнаружено усиление вклада 8Be в диссоциацию с множественностью α-частиц.</p></abstract><trans-abstract xml:lang="en"><p>The correlation between the formation of the unstable 8Be nucleus and accompanying α-particles in the fragmentation of relativistic 16О, 22Ne, 28Si, and 197Au nuclei in a nuclear track emulsion is investigated. The 8Be decays are identified in a wide energy range by invariant masses calculated from 2α-pair opening angles. The adopted approximations were verified by data on fragmentation of 16O nuclei in a hydrogen bubble chamber in a magnetic field. An increase in the 8Be contribution to the dissociation with an α particle multiplicity is found.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ядерная эмульсия</kwd><kwd>диссоциация</kwd><kwd>инвариантная масса</kwd><kwd>релятивистские фрагменты</kwd><kwd>ядро 8Be</kwd><kwd>альфа частицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nuclear emulsion</kwd><kwd>dissociation</kwd><kwd>invariant mass</kwd><kwd>relativistic fragments</kwd><kwd>8Be nucleus</kwd><kwd>alpha particles</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">Zarubin P.I. // Lecture Notes in Physics, vol 875.
