Анотація

В рамках теорiї розпадiв Гольдбергера i Ватсона a-розпад розглядається як перехiд мiж початковим зв’язаним станом ядра та станами неперервного спектра з a-частинкою. В квазикласичному наближеннi виведенi базиснi хвильовi функцiї для a-розпаду з довiльним орбiтальним кутовим моментом. Альфа-частинка описується квадратично-iнтегровним хвильовим пакетом, утвореним цими функцiями, амплiтуда якого ззовнi ядра експоненцiйно росте аж до хвильового фронту. Аналiзується ефект Мошинського пошкодження хвильового фронту. Виведений вираз для швидкостi розпаду апроксимується квазикласичною формулою.
