Анотація


Послідовний квантовий підхід до обчислення спектрів електронно-гамма-ядерних переходів (набору колебательно-обертальних сателітів в молекулі) в багатоатомних молекулах застосований до визначення спектроскопічних даних про ймовірності колебательно-ядерних переходів при випромінюванні і поглинанні ядра 186Re (E(0) g = 186.7 кеВ ) в молекулі ReO4. Основні труднощі при оцінці відповідних матричних елементів пов’язана з визначенням значень bsγ- – нормованих зрушень гамма-активного розпаду. Відомо, що якщо молекула має єдине нормальне коливання даного типу симетрії, то відповідні значення bsγ- – можуть бути знайдені з добре відомих умов Еккарта, умови нормування і даних про симетрію молекули.

Ключові слова


електрон-гамма-ядерний спектр; ймовірність коливально-ядерних переходів
