Ефективний релятивістський енергетичний підхід в комбінації з багаточастинкової теорією збурень з неемпіричним нульовим наближенням використуються для розрахунку перетинів електронного збудження за рахунок зіткнень для ряду складних релятивістських багатоелектронних систем. Релятивістська багаточастинкова теорія збурень поряд з ефективною калібрувально-інваріантної схемою використуються для генерації оптимального одноелектронного уявлення Дірака-Кона-Шама-Дебая-Хюккеля. Наведены результати релятивістського розрахунку (з урахуванням обмінних і кореляційних поправок) перетинів електрон-зіткнень збудження неоноподібного іона кріптону і проведено порівняння з альтернативними результатами розрахунків на основі R-матричного методу в наближенні Брейта-Паулі, в релятивістському наближенні спотворених хвиль і на основі R-матричного методу в поєднанні з наближенням Дірака-Фока.
