Nonlocal separable potential and p-α scattering

Нелокальный раэделяемый потенциал и p-α рассеяние

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

Summary

A study has been made of thes-,p-,d- andf-wave p-α scattering phase shifts up to a bombarding energy of 18 MeV, using a nonlocal separable interaction. Calculations have been made in the co-ordinate representation in which the Coulomb forces have been taken into account exactly. The separable-potential model of the nucleon-alpha interaction is found to be satisfactory.

Riassunto

Si è eseguito uno studio degli spostamenti di fase dello scattering p-α nelle ondes, p, d ef sino ad un’energia di bombardamento di 18 MeV, facendo uso di un’interazione separabile non locale. Si sono effettuati i calcoli nella rappresentazione delle coordinate in cui si è tenuto esattamente conto delle forze di Coulomb. Si trova che il modello di potenziale separabile per l’interazione nucleone-α è soddisfacente.

Реэюме

Испольэуя нелокальное раэделяемое вэаимодействие, исследуются фаэовые сдвигиs-,p-,d-f-волн в процессе p-α рассеяния при знергиях падаюших частиц вплоть до 18 МзВ. Вычисления проводятся в координатном представлении, в котором кулоновские силы учитываются точно. Получается, что модель раэделяемого потенциала для рассеяния нуклона на альфа-частице является удовлетворительной.
