Article

Summary

It is pointed out that the difficulties arising from the interpretation of the (3He, α) reactions can be overcome by applying the Feynman-diagram technique. The cluster triangle graph contributions are studied in order to disclose the reaction mechanisms. Angular distributions up to 90° for the reaction10B(3He, α)9B at 5.5 MeV and excitation function at 30° are calculated. Satisfactory agreement with experimental data is obtained.

Вклад кластерного механиэма в реакцию10B(3He,α)9B

Реэюме

Отмечается, что трудности, воэникаюшие при интерпретации реакций (3He,α), могут быть преодолены с помошью применения диаграммной техники Фейнмана. Исследуется вклад кластерных треугольных графиков, чтобы понять механиэм реакций. Вычисляются угловые распределения вплоть до 90° для реакции10B(3He,α)9B при 5.5 MзB и функция воэбуждения при 30°. Получено удовлетворительное согласие с зкспериментальными данными.

Riassunto

Si indica come le difficoltà che sorgono nell’interpretazione delle reazioni (3He, α) possono essere superate applicando le tecniche dei grafici di Feynman. Allo scopo di individuare i meccanismi di reazione si studiano i contributi relativi a grafici triangolari di tipo «cluster». Si calcolano la distribuzione angolare fino a 90° della reazione10B(3He, α)9B a 5.5 MeV e la funzione di eccitazione a 30°. Si ottiene un accordo soddisfacente con i risultati sperimentali.
