The decay of133Ba and nuclear transitions in133Cs

Распад133Ba и ядерные переходы в133Cs

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

Summary

The relative gamma-ray intensities in the decay of133Ba are determined by means of lithium-drifted germanium detectors. A reasonable value of the logft of an EC second forbidden transition is obtained. The experimental electromagnetic transition strengths connecting 3 excited states and the ground state of133Cs are found to agree fairly well with the theoretical estimates of the Kisslinger-Sorensen model.

Riassunto

Si sono determinate, per mezzo di rivelatori a germanio, le intensità gamma relative nel decadimento del133Ba. È stato ottenuto un valore ragionevole per il logft di una transizione di cattura elettronica due volte proibita. I valori sperimentali delle probabilità di transizione elettromagnetiche fra tre stati eccitati e lo stato fondamentale del133Cs sono in buon accordo con le previsioni teoriche secondo il modello di Kisslinger Sorensen.

Реэюме

С помошью литиевых дрейфовых германиевых детекторов определяются относительные интенсивности γ-лучей при распаде133Ba. Получается раэумная величина logft для второго эапрешенного перехода. Экспериментальные интенсивности злектромагнитных переходов, свяэывающих трехкратно воэбужденные состояния с основным состоянием133Cs довольно хорощо согласуются с теоретическими оценками по модели Кислингера-Соренсена.
