Meson and isobar degrees of freedom in light nuclei

Мезонные и изобарические степени свободы в легких ядрах

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

Summary

The role of mesonic and isobar degrees of freedom in various electromagnetic processes is reviewed for light nuclei. Special emphasis is laid on the deuteron, which allows the cleanest answers within the non-relativistic framework. The origin of the photonuclear enhancement with respect to both exchange forces and exchange currents is discussed in detail.

Riassunto

Si riesamina il ruolo dei gradi di libertà mesonici e isobarici in vari processi elettromagnetici per i nuclei leggeri. Si da particolare rilievo al deuterone, che dà risposte più precise nell’àmbito non relativistico. Si discute in dettaglio l’origine dell’incremento fotonucleare sia rispetto alle forze di scambio che alle correnti di scambio.

Резюме

Анализируется роль мезонных и изобарических степеней свободы в различных электромагнитных процессах в легких ядрах. Особое внимание уделяется дейтрону, который позволяет получить четкие ответы в рамках нерелятивистского подхода. Подробно обсуждается происхождение фотоядерного усиления обменных сил и обменных токов.
