Научная тема: «ИССЛЕДОВАНИЕ ДИНАМИЧЕСКИХ ЭФФЕКТОВ СПОНТАННОГО ДЕЛЕНИЯ 252СГ И ГЕНЕРАЦИИ НЕЙТРОНОИЗБЫТОЧНЫХ ЯДЕР В ФОТОДЕЛЕНИИ»
Специальность: 01.04.16
Год: 2009
Отрасль науки: Физико-математические науки
Основные научные положения, сформулированные автором на основании проведенных исследований:
  1. Обоснован и применен в эксперименте новый метод определения независимых выходов осколков деления - выходов коррелированных пар. С применением выхода коррелированных по заряду пар осколков введена методика определения абсолютного значения множественности нейтронов деления. Определены независимые выходы вторичных и первичных коррелированных пар по ядерному заряду осколков. Впервые получено распределение множественности нейтронов зарядовых пар Zr-Ce, Мо-Ва, Ru-Xe и Pd-Te осколков двойного деления. Найдено, что повышенная эмиссия нейтронов (и=6-10), которая наблюдена только у пары Мо-Ва, возможна, когда осколки Ва находятся в гипердеформированном состоянии.
  2. Определены выходы осколков безнейтронного двойного деления, при котором происходит холодная фрагментация. Из результатов эксперимента оценен диапазон энергий возбуждения отдельных пар осколков. Определена новая область холодной и деформированной фрагментации в районе ядер, близких к магическим ядрам с Z=28 и N=50. Также определены массы ядер, участвующие в холодной и деформированной фрагментации одновременно. Впервые наблюдено холодное симметричное деление.
  3. Получены новые данные о распределении энергии возбуждения в зависимости от массы и полной кинетической энергии осколков двойного деления 252Cf. Рассмотрен механизм эмиссии гамма-лучей, отвечающий за разрядку энергии и углового момента, в зависимости от полной кинетической энергии и массы осколков. Определены значения угловых моментов осколков деления и рассмотрены связи внутренних и коллективных переменных при формировании углового момента.
  4. Впервые при исследовании тройного деления получены независимые выходы вторичных и первичных коррелированных пар по заряду осколков. Получено распределение множественности нейтронов зарядовых пар. Найдены зависимости интегральных характеристиках эмиссии гамма-квантов в зависимости от кинетической энергии ядер Не, Ве и С. Определены средние угловые моменты пар осколков тройного деления 252Cf с эмиссией ядер Не. Выявлена зависимость их значений от амплитуды поперечных колебаний, деформационной энергии и моментов инерции осколков на их предразрывной и разрывной стадиях процесса деления.
  5. Показано, что реакция фотоделения может быть успешно использована для получения интенсивных радиоактивных нейтроноизбыточных пучков ядер средних масс.
