Квадратичный эффект Зеемана и сверхтонкое магнитное экранирование рассчитаны в гелиеподобных ионах в основном (1s)2 состоянии с помощью теории возмущений. Численные значения получены для диапазона зарядов ядра Z = 6 – 32. Зеемановское расщепление оценивается путем решения уравнения Дирака в кулоновском поле с конечным ядром с использованием B-сплайнов, построенных в рамках метода ДКБ. Вклады ведущего порядка, а также однофотонные обменные поправки рассматриваются в рамках строгого подхода КЭД. Рассчитанные константы ядерного магнитного экранирования могут быть использованы для определения ядерных магнитных моментов, в то время как квадратичный эффект Зеемана имеет значение для прецизионных измерений энергий переходов в гелиеподобных ионах в ловушках Пеннинга.
