Изучаются основные особенности динамики деления при мгновенном делении: увеличение барьера, динамика перехода от седловой к разрывной стадии, мюонная конверсия и характеристическое рентгеновское излучение от осколков деления дают многостороннюю информацию о динамике деления и свойствах осколков. Продемонстрировано влияние подавления деления в мюонных атомах 238U на форму ГДР и вероятность его безрадиационного возбуждения в переходах 3p−1s. Предложена простая интерпретация зависимости наблюдаемой ширины ГДР от энергии.</p></abstract><trans-abstract xml:lang="en"><p> Abstract—In muonic atoms of 238U, nuclei can undergo prompt fission via nonradiative muon transitions: 2p−1s, 3p−1s, 3d−1s, etc. The main features of fission dynamics in prompt fission are studied: barrier increase, saddle-to-scission transition dynamics, muon conversion, and characteristic X-ray emission from fission fragments provide comprehensive information on fission dynamics and fragment properties. The effect of fission suppression in muonic 238U atoms on the GDR shape and the probability of its radiationless excitation in the 3p−1s transitions is demonstrated. A simple interpretation of the energy dependence of the observed GDR width is proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гигантский дипольный резонанс</kwd><kwd>безрадиационное возбуждение ядра</kwd><kwd>мюонные атомы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>giant dipole resonance</kwd><kwd>radiationless excitation of nuclei</kwd><kwd>muonic atoms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">В заключение автор хотел бы выразить благодарность М.
