A global potential for the interaction of alpha-particles with light nuclei?

Глобальный потенциал для вэаимодействия альфа-частиц с легкими ядрами

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

Summary

Different analytical forms for the repulsive part of the alpha-nucleus interaction are discussed. For the system12C+α (2.8 MeV ⩽E α<6.5 MeV) purely real potentials reproduce the experimental quantitiesE x ,Γ x and dσ/dΩ quite satisfactorily. Numerical results and physical considerations advocate application of a repulsion proportional toV c(1 − (r/R c)2).

Riassunto

Si discutono diverse forme analitche per la parte repulsiva dell’interazione tra particella α e nucleo. Per il sistema12C + α (2.8 MeV ⩽E α⩽ 6.5 MeV) potenziali puramente reali riproducono in maniera abbastanza soddisfacente le quantità sperimentaliE x ,Γ x e dσ/dΘ. Risultati numerici e considerazioni fisiche sono a favore dell’applicazione di una repulsione proporzionale aV c(1 − (r/R c 2).

Реэюме

Обсуждаются раэличные аналитические формы для отталкивательной части вэаимодействия альфа-частиц с ядрами. Для системы12C +α (2.8 МзВ⩽E α<6.5 МзВ) чисто вешественные потенциалы удовлетворительно воспроиэводят величиныE x ,Г x и dσ/dΘ. Численные реэультаты и фиэические соображения укаэывают, что отталкивание пропорциональноV c(1 − (r/R c 2).
