WalletCraft: A new evaluation of the properties of ground state and long-lived isomers for all known nuclides*

The Nuclear Wallet Cards is a collection of selected properties of all known nuclides and their long-lived isomeric states. Introduced in 1971, it has been produced at the National Nuclear Data Center (NNDC) since 1985. The evaluations have been disseminated as a printed booklet, and through an online application hosted on the NNDC website (www.nndc.bnl.gov/wallet). The last edition of the Nuclear Wallet Cards was produced by J.K.Tuli in 2011, and a revision is long overdue.

As part of the Evaluated Nuclear Structure Data File (ENSDF) modernization project, the Wallet Cards have also undergone a full update, resulting in an entirely new database called WalletCraft.

Based on an expansible object-oriented format, WalletCraft was designed to include not only evaluated quantities, but also all the experimental values that were used to calculate them. This will simplify incremental revisions of the recommended values, that will be readily updated whenever new experimental determinations become available.

The first release of WalletCraft, which includes the inclusion of all source measurements, is currently being completed at the NNDC and will be made available as a web-based application in the coming months. Details of the WalletCraft database and of the new evaluation will be presented.
