The French Center for Nuclear Mass Spectrometry signed a memorandum of understanding (MOU) with the CAS Institute of Modern Physics (IMP) recently in Lanzhou to transfer the task of atomic mass evaluation to the latter. The document was signed by IMP director XIAO Guoqing, and Director of the Atomic Mass Data Center (AMDC) Georges Audi.
According to the MOU, the CAS institute will take over the task of AMDC for the world's determination of the atomic masses in the future.
Mass is the primary physical quantity of fundamental significance for an atomic nucleus. Almost all of the studies and application in the field of atomic physics are closely related to the atomic mass. So it is of vital importance for scientists to make a top-quality evaluation of the atomic mass. Since 1955, there have been six editions of bulletins published to catalogue various nuclide masses. The latest edition was published in 2003.
Equipped with he largest research facility for heavy ions in this country, IPM boasts one of the most important hubs of nuclear research in the world today.
