Calculs de transitionsE2, M1 et mélange de bandes avec plusieurs nucléons de valence

Вычисления переходовE2, M1 и смешивание зон для ядер с несклькнми валентностями.

Il Nuovo Cimento A (1965-1970)

Summary

Difficulties in performing the calculations ofE2, M1 matrix elements and incoherences in existing literature are reported for the mixing of bands with several valence nuclei. Various prescriptions may lead to rather different results: an illustration is given for the23Na nucleus.

Résumé

Des difficultés pour conduire le calcul des éléments de matrice multipolairesE2 etM1 de même que des incohérences dans la littérature existante sont évoquées à propos du mélange de bandes avec plusieurs nucléons de valence. Les diverses prescriptions peuvent conduire à des résultats sensiblement différents: une illustration en est donnée pour le noyau23Na.

Riassunto

Si rievocano alcune difficoltä nell'eseguire i calcoli degli elementi di matrice multipolariE2 eM1 come pure alcune incoerenze della letteratura esistente concernenti la mescolanza di bande con molti nucleoni di valenza. Le varie prescrizioni possono condurre a risultati notevolmente diversi; si illustra il caso del nucleo23Na.

Резюме

Отмечаются трудности, связанные с вычислениями матричных элементов перходовE2, M1, и несоответствия в литертуре для смешивания зон случае ядер с несколькими валентностями. Различные описания могут привести к довольно существенно различающимся результатам. Анализируется случай для ядра23Na.
