Résumé
Le déplacement Lamb S dans l'argon hydrogénoïde (Z=18) a été mesuré dans une expérience de temps de vol avec quenching en champ électrique. Nous trouvons S=(38,0±0,6) THz où l'erreur inclut l'erreur statique 1σ de 0,35 THz et une erreur systématique estimée à 0,48 THz.

Abstract
The Lamb shift S in hydrogenlike argon (Z=18) has been measured by a motional electric field quenching time-of-flight experiment. We find S = (38.0 ± 0.6) THz where the error includes 1σ statistical error of 0.35 THz and an estimated systematic error of 0.48 THz.

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.
