Nonlocal forces and dipole sum rules

Нелокальные силы и дипольные правила сумм

Il Nuovo Cimento A (1965-1970)

Summary

A realistic separable nucleon-nucleon interaction determined recently has been applied to study the nonlocal effects of nuclear forces in the integrated photoabsorption cross-section. Calculations performed in the electric-dipole approximation and with a Fermi gas nuclear model indicate a good agreement with experimental data in the heavy-nuclei region.

Riassunto

Si è applicata allo studio degli effetti non locali delle forze nucleari nella sezione d'urto di fotoassorbimento integrata una interazione separabile nucleone-nucleone aderente alla realtà, determinata recentemente. I calcoli condotti con l'approssimazione di dipolo elettrico e con un modello nucleare ispirato al gas di Fermi indicano un buon accordo con i dati sperimentali nella regione dei nuclei pesanti.

Резюме

Реальное разделяемое нуклон-нуклонное взаимодействие, определенное ранее, было применено к исследованию нелокальных эффектов ядерных сил в интегральном поперечном сечении фотопоглощения. Проведенные вычисления в приближении электрического диполя и с ядерной моделью Ферми газа показывают хорошее согласие с эксперименталяными данными в области тяжелых ядер.
