The 2012 Atomic Mass Evaluation and the Mass Tables

The new evaluation of the Atomic Masses, Ame2012, has just been released. It represents a major step in the history of the 60 year old Atomic Mass Evaluation based on the method developed by Wapstra. This new publication includes all material available to date. Some of the policies and procedures used in our evaluation are reported, together with an illustration of one specially difficult case, the energy available for the 102Pd double-electron capture. The observation of the mass surface reveals many important new features. We illustrate this statement by the double magicity of 270Hs at N = 162 and Z = 108.
