10th Edition 2018
New machine developments and improvements at major nuclear centres worldwide are the main source of discovery of new elements, isotopes and new experimental results. This very active area of research provides a continuous source of new data. Our mission is to maintain, develop and update the Karlsruhe Nuclide Chart with concise, up to date information on all experimentally observed nuclides.
For now almost 60 years, the Karlsruhe Nuclide Chart has provided scientists and students with structured, accurate information on the half-lives and decay modes of radionuclides, as well as the energies of emitted radiation. Beyond the more traditional physical sciences such as health physics and radiation protection, nuclear and radiochemistry, and astrophysics, the Chart is now in wide and common usage in the life and earth sciences (biology, medicine, agriculture, geology, etc.). An important characteristic of the Chart is its great didactic value in education and training in the nuclear sciences. It is used in training programmes worldwide and is a valuable and welcome addition to the many books on nuclear science including school textbooks. Although many nuclear data sources are available on the internet, the Karlsruhe Nuclide Chart provides a unique overview of current knowledge and is for many the preferred medium for ease of use, convenience and practicality.
The new edition of the “Karlsruher Nuklidkarte” contains new and updated radioactive decay data on 696 nuclides (47 new nuclides) not found in the previous (2015) edition. In total, nuclear data on 4040 experimentally observed ground states and isomers are presented.
The new names and chemical symbols of elements 113, 115, 117, and 118 have been updated in the Karlsruhe Nuclide Chart. In 2016, IUPAC agreed on the names nihonium (113, symbol Nh), moscovium (115, Mc), tennessine (117, Ts), and oganesson (118, Og). Until now, these elements have been referred to simply by the number of protons in each atom – 113, 115, 117 and 118, respectively. Nihonium references the Japanese name for Japan. The element was discovered at the RIKEN Nishina Center for Accelerator Science. Moscovium was named after the Moscow region, the location of the Joint Institute for Nuclear Research in Dubna. Tennessine recognises the US state of Tennessee and the local contributions made to the discovery by the Oak Ridge National Laboratory and Vanderbilt University. Oganesson honours the nuclear physicist Yuri Oganessian, who has played a leading role in the search for new elements. Most recent values of the atomic weights, isotopic abundances and cross sections are included together with the thermal fission yields for both 235U and 239Pu. For twelve elements, a range of atomic weights is given to reflect the isotopic variability in natural materials. The accompanying booklet again contains the multi-lingual “Explanation of the Chart of the Nuclides” in English, German, French, Spanish, Russian, and Chinese, updated to reflect changes in the Chart. The Reduced Decay Schemes section initiated in previous editions, and used to describe in detail how the nuclide box contents should be interpreted with reference to the nuclide decay schemes, has been considerably expanded to include a total of 88 examples.
This new 10th Edition of the Karlsruhe Nuclide Chart is the result of a collaboration between Zsolt Sóti from the EC’s Joint Research Centre and Joseph Magill and Raymond Dreher from the Nucleonica team. An online version of the Karlsruhe Nuclide Chart Online is available through the Nucleonica nuclear science portal (www.nucleonica.com).
This new 10th Edition coincides with the 60th anniversary of the Karlsruhe Nuclide Chart - the first edition appeared in 1958. Sadly, Gerda Pfennig, “Mother” of the Karlsruhe Nuclide Chart, died on 16 February 2017 aged 86. Since this first edition, Frau Pfennig has co-authored all editions of the Chart including the 9th Edition in 2015. In the field of nuclear data Frau Pfennig was both conscientious and dedicated and an inspiration to her colleagues.
Since 1st January 2012, the management of the Karlsruhe Nuclide Chart has been taken over by Nucleonica GmbH - a spin-off company of the EC's Joint Research Centre (JRC). Through a license agreement with the JRC, Nucleonica GmbH has exclusive rights to further develop and market the current and future editions of the Chart.
