Анотація

У роботi дослiджено процес фотонародження ee+ пари з врахуванням поляризацiйного каскаду (народження та послiдовної анiгiляцiї пари в один фотон) в сильному магнiтному полi. Проаналiзовано кiнематику та отримано вираз для загальної амплiтуди процесу. Знайдено радiацiйну поправку при народженнi пари фотоном на найнижчi рiвнi Ландау для випадку, коли енергiя початкового фотона має
значення, близьке до порогового. Проведено порiвняння з процесом народження ee+ пари одним фотоном.
