Atomic Mass Data Center

The "Atomic Mass Data Center" AMDC and its electronic bulletin aim at being a meeting place where information on masses (experimental, evaluation or theory) can be exchanged. All those working on topics related to atomic masses can thus keep the community informed (in a non-official way) on the latest developments of their own work.
One of the goals assigned to the AMDC is to give progress reports on the " Atomic Mass Evaluation" AME and to put at the user's disposal the most recent atomic masses.

Le "Centre de Données sur les Masses Atomiques" AMDC et son bulletin électronique se veulent être un lieu de rencontre et d'échange sur les masses (expérimentales, évaluées ou théoriques). Tous ceux qui travaillent sur des sujets relatifs aux masses atomiques peuvent ainsi informer (de façon non-officielle) la communauté des derniers développements de leurs propres travaux.

Une des missions de l'AMDC est de donner des informations sur l'état d'avancement des travaux de l'"Evaluation des Masses Atomiques" AME et de mettre à la disposition des utilisateurs les masses atomiques les plus récentes.
