Three-body correlations and tensor forces

Трехчастичные корреляции и тензорные силы

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Three-body forces resulting from three-body cluster terms are taken into account. An expression for the three-body cluster energy is obtained. Numerical claculations are carried out to get values for binding energies in different doubly-closed-shell nuclei by using nucleon-nucleon interaction with tensor forces. The contribution of the three-body correlations to the binding energies of these nuclei is investigated. Moreover, the effect of the tensor forces is tested.

Riassunto

Si prendono in considerazione forze a tre corpi che risultano da termini di ammassi a tre corpi. Si ottiene un'espressione per l'energia di ammassi a tre corpi. Si fanno calcoli numerici per ottener valori dell'energia di legame in differenti nuclei a strato doppiamente chiuso usando l'interazione nucleone-nucleone con forze tensoriali. Si studia il contributo delle correlazioni a tre corpi alle energie di legame di questi nuclei. Inoltre si controlla l'effetto delle forze tensoriali.

Резюме

Рассматриваются трехчастичные силы, которые вытекают их трехчастичных кластерных членов. Получено выражение для энергии трехчастианого кластера. Проводятся численные расчеты эначений энергий связи для различных ядер с дважды замкнутой оболочкой, используя нуклон-нуклонное взаимодействие с тензорными силами. Исследуется вклад трехчастичных корреляций в энергии связи этих ядер. Рассматривается также влияние тензорных сил.
