Аннотация
Проанализированы доступные источники литературы (более 80 работ) по сечениям 9 реакций взаимодействия p, d, α с ядром 11B. Сечения реакций (p, γ), (α, γ), (p, α), (d, γ), (p, n), (α, p), (d, n), (d, α), (d, p) играют основную роль в реакторах управляемого термоядерного синтеза и в звездных процессах. Оценка сечений проводилась путем отбора основной работы, в которой измерения данных было сделано с минимальными погрешностями и на современном уровне. Остальные работы использовались для расширения интервала анализируемых данных методом сшивания в энергетических интервалах перекрытия. Затем подготовленная цепь выстроенных данных описывалась по методу сплайн-апроксимации полиномом третьей степени по энергии. Значения узловых точек и коэффициентов сплайн-функции приведены в таблицах, а качество описания представлено на рисунках.
