Il Nuovo Cimento A (1965-1970)

Summary

In this paper the partial-capture rates of muons in11B going to11Be(g.s.) and11Be (320 keV), as well as the hyperfine effect in the transition to11Be*, are studied. Comparing these results with the beta-decay of11Be and the electromagnetic transition11Be* →11Be, we can derive some conclusions on the nuclear structure of the bound states of11Be. We also discuss some possible experiences which can give information on the pseudoscalar form factor in weak interactions.

Riassunto

In questo articolo si studiano i rapporti di cattura parziale dei muoni in11B che si trasforma in11Be(g.s.) e11Be(320 keV) e l’effetto iperfine nella transizione a11Be*. Confrontando questi risultati con il decadimento β dell’11Be e con la transizione elettromagnetica11Be* →11Be, si possono trarre alcune conclusioni sulla struttura nucleare degli stati legati dell’11Be. Si discutono alcune possibili esperienze che possono fornire informazioni sul fattore di forma pseudoscalare nelle interazioni deboli.

Реэюме

В зтой статье исследуются интенсивности парциальных эахватов мюонов в ПВ, который переходит в11Be (основное состояние) и11B (320 кзВ), а также влияние сверхтонкой структуры на переход в11Be*. Сравнивая зти реэультаты с бета-распадом пВе и злектромагнитным переходом11Be* →11Be, мы можем сделать некоторые эаключения о ядерной структуре свяэанных состояний11Be. Мы также обсуждаем некоторые воэможные зксперименты, которые могут дать информацию о псевдоскалярном форм-факторе в слабых вэаимодействиях.
