Résumé
A partir d'une tendance systématique dans les spectres de photoémission X des terres rares et des éléments voisins, nous suggérons que les niveaux 5s, 5P_3/2 et 4d dans les actinides peuvent présenter de forts effets à plusieurs électrons ; des données disponibles sur les actinides permettent de confirmer les prédictions précédentes.

Abstract
On the basis of systematic trends in X-ray photoemission core-level spectra of the rare earth elements and the adjacent elements, it is suggested that the 5s, 5p_3/2 and 4d levels of the actinides should exhibit strong many-electron effects. The available actinide data appears to support the above predictions.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

• If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
• You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
• You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
