Levels in149Eu from the (p, 4nγ) reaction

Уровни в149Eu из реакции (p, 4nγ)

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

Summary

Transitions in149Eu are studied by gamma-ray and conversion electron measurements following the152Sm (p, 4n) reaction. A level scheme is proposed and compared with findings by other authors. The experimental results for the negative-parity states are compared with the predictions of the interacting-boson-fermion model.

Riassunto

Studio delle transizioni nell’isotopo149Eu mediante misure di raggi gamma ed elettroni di conversione prodotti nella reazione152Sm (p, 4n). Lo schema di livelli proposto è paragonato coi risultati di altri autori ed i risultati sperimentali riguardanti i livelli a parità negativa sono confrontati con le previsioni del modello a bosoni-fermioni interagenti.

Резюме

Исследуются переходы в149Eu, используя измерения гамма-лучей и измерения конверсии электронов, образованных в реакции152Sm (p, 4n). Предлагается схема уровней й проводится сравнение с результатами других авторов. Экспериментальные результаты для состояний с отрицательной четкостью сравниваются с предсказаниями модели взаимодействующих бозонов и фермионов.
