Анотація

Форми спектральних лiнiй плазми мiстять iнформацiю щодо параметрiв плазми i можуть бути використанi для її дiагностики. Отримано формулу з функцiєю Мейєра для оператора зiткнень електронiв плазми в зовнiшньому магнiтному полi. В рамках деякого наближення розглядається взаємодiя мiж випромiнюючими системами (воднеподiбними йонами) та електронами плазми. Розраховано амплiтуду оператора зiткнень йонiв Ar+17, V+22, Cr+23, Fe+25 та Ag+46 в iнтервалi густин 1018–1026 см−3 при температурах 106–1010 К в дуже сильному магнiтному полi 100–10 000 T. Результати для Лайман-альфа лiнiї добре узгоджуються з експериментальними даними та iншими теоретичними результатами.
