WWW Chart of the Nuclides here is based on the compilation of
experimental data until 2008 by H. Koura (JAEA), T. Tachibana (Waseda University), and
J. Katakura (JAEA), beta-decay half-lives estimated, by T. Tachibana, with the Gross Theory
[T. Tachibana, M. Yamada, Proc. Int. Conf. on exotic nuclei and atomic masses,
Arles, 1995, p.763], and alpha-decay half-lives based on the reference of V.E. Vola, Jr. and
G.T. Seaborg, J. Inorg. Nucl. Chems., 28, 741 (1966) and newly adjusted parameter values.
A printed version of Chart of the Nuclides 2010, compiled by
T. Tachibana, H. Koura and J. Katakura, JNDC and Nuclear Data Center, JAEA (2010), is
available now.
In this
WWW Chart of the Nuclides, a decay mode of ground state is
indicated with
decay mode pattern. A half-life
of each nuclide is shown with
color codes
and numerical values. For the nuclides which have an isomer with a half-life longer than its ground state,
the half-life of the isomer is shown in the chart. In such cases, a small rectangule is displayed at the
right top corner. The color of the small rectangule is corresponding to the half-life of the ground state.
By clicking a box of each nuclide, information on the nuclide is shown, which contains
spin and half-life,
mass,
strong gamma-rays from nuclear decay,
decay data, and links to
figures and
tables of cross-section data stored in Japanese evaluated nuclear data library
JENDL-4.0.
When a box of atomic numbers located at the left side is clicked, an isotope list of corresponding element is
displayed.
WWW Chart of the Nuclides 2010 was created by using
gd2.0.35
which was originally developed by
Thomas Boutell and is now maintained by
Pierre-A. Joye under the umbrella of PHP.net.
