The 'Nucleide' Database for Decay Data and the 'International Decay Data Evaluation Project'

摘要

A database and an application, known as "Nucleide", have been developed with the aim of offering users easy access to nuclear and atomic decay data simply by clicking on buttons. The aim of this table is to provide recommended data for nuclides of special interest for metrology or practical applications, such as nuclear medicine, monitoring and reactor shielding, etc. Primary recommended data comprise half-lives, decay modes, branching fractions and their uncertainties and the energies and emission intensities for X- and gamma-rays, electron emissions and alpha particles. In order to update the data and regularly add new evaluations, a new international collaboration has been formed, the Decay Data Evaluation Project (DDEP), comprising evaluators from France, Russia, Germany, United Kingdom, Spain and the United States. Its objective is to provide carefully recommended values which may eventually become standard data. The results of this work are available on CD-ROM or in print.
