Extreme breathing excitations of atomic nuclei

Экстремальные дыхательные возбуждения атомных ядер

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

Summary

The existence of extreme breathing nuclear states is predicted in the framework of coherent density fluctuation model. The energies of these states are comparable with the nuclear binding energies. The nuclear size is considerably larger in the excited states than in the ground state. There exists a threshold with respect to the mass numberA for the appearance of the breathing vibrations. The extreme nuclear states are discussed in relation with the collective mechanism in deep inelastic proton-nuclei scattering, in which a formation of highly excited system is suggested.

Riassunto

Si prevede l'esistenza di stati nucleari estremi che respirano nell'ambito del modello di fluttuazione di densità coerente. Si confrontano le energie di questi stati con le energie nucleari di legame. La dimensione nucleare è notevolmente maggiore negli stati eccitati che nello stato fondamentale. Esiste una soglia rispetto al numero di massaA per la comparsa di vibrazioni che respirano. Si discutono gli stati nucleari estremi in relazione al meccanismo collettivo dello scattering protone-nucleo inelastico profondo, in cui si suggerisce la formazione di un sistema altamente eccitato.

Резюме

Существование экстремальных дыхательных состояний ядер предсказывается в рамках модели когерентных флуктуаций плотности. Энергии этих состояний порядка энергии связи ядер. Размеры ядер в возбужденных состояниях существенно превьппают размеры в основном состоянии. Существует порог возникновения дыхательных состояний по массовому числуA. Эти экстремальные состояния ядер обсуждаются в связи с коллективным механизмом в глубоконеупругом протонядерном рассеянии, в котором предполагается существование высоковозбужденной системы.
