Анотація


Викладені теоретичні основи нового апарату релятивістської операторної теорії збурень (ОТЗ) в спектроскопії багатоелектронного атома в електромагнітному полі, об'єднаного з формалізмом релятивістської багаточастинкової теорії збурень для вільного багатоелектронного атома. В якості ілюстрації можливостей представленого підходу представлені результати оцінки деяких енергетичних і спектральних параметрів для ряду атомів. Релятивістський метод OPЗ тестується для таких багатоелектронних систем як Fr і Tm. Новий підхід розроблений для послідовного опису ефекту Штарка в багатоелектронних атомах в сильному зовнішньому електромагнітному полі
