Atomic mass and characteristic constants for nuclear ground states are basic data for nuclear physics, and necessary ones for basic researches, theoretical calculations, as well as many applied researches. The atomic mass of exotic nuclei quite far from the valley stability are also very important for astrophysics researches. The above-requirement is paid attention to in our setting up this file. The recent and as many as possible data (such as the half-lives of the new nuclides ~(202)Pt, ~(208)Hg and ~(185)Hf and the mass excess of ~(199)Ir, which were produced and distinguished by Chinese scientists ) have been collected, and put into the computer-based data file in brief table format.

The atomic mass of exotic nuclei quite far from the valley stability is also very important for astrophysics researches. The above-requirement is paid attention to in our settings up this file. The recent and as many as possible data (such as the half-lives of the new nuclides ~ (202) Pt, ~ (208) Hg and ~ (185) Hf and the mass excess of ~ (199) Ir, which were produced and distinguished by Chinese scientists) have been collected and put into a computer-based data file in brief table format.
