Nucleonica Physical Constants updated to 2018 CODATA recommended values

August 13th, 2019

The values of the physical constants used in Nucleonica are recommended by CODATA and are the latest available. Termed the “2018 CODATA recommended values” they are recognized worldwide for use in science and technology. The values became available on 20 May 2019 and replaced the 2014 CODATA set. They are based on all data available until 31 December 2018.NewPCs-2019Of particular important to the Nucleonica applications, IUPAC is recommending a new definition of the mole based on a specified number of elementary entities:
The mole, symbol mol, is the SI unit of amount of substance. One mole contains exactly 6.022 140 76 × 1023 elementary entities. This number is the fixed numerical value of the Avogadro constant, NA, when expressed in mol−1, and is called the Avogadro number.

Metastable states in the Karslruhe Nuclide Chart

July 24th, 2019

Qu. (from M. R. KTE Karlsruhe, Germany):
Dear Nucleonica Team,
I have always wondered what the criteria are to show the metastable state of a nuclide on the chart. The first guess would be the half life of the state. But I found for example the nuclide Rn-214 which shows a metastable state of only 0,69 ns. Is there an arbitrary threshold just below that number where you show the state on the chart if it is above? If the threshold depends on the half life, is there a scientific reason for that threshold? Are all states shown that are above that threshold?
Rn214Ans. (Nucleonica Team)
Metastable states, which do not undergo alpha or beta decays or spontaneous fission, i.e. decay only by isomeric transition are shown (usually) only if their half-life is larger than 1 s (to save space).

Rn 214 excited states Rn 214m and Rn 214n have been observed, both with alpha decay to Po 210. Although their half-lives are less than 1s they are shown in KNC. In this way the users of KNC can know that the alpha emission is not from the ground state of Rn 214 and can have higher energy than the Q-value of ground state to ground state decay.
In some particular cases when the metastable state has an important role in a decay chain or in nuclear physics theory, it is presented even it decays only with isomeric transition and has a half-life shorter than 1s.
There is an interesting article on wikipedia.

New publication on the Karlsruhe Nuclide Chart

May 27th, 2019

Obtaining nuclear data is an international activity with new and updated data constantly being determined by thousands of scientists at major research centres worldwide. Because of the large amounts of data generated and the formats used to store these data, the field of nuclear data is highly specialised. To make the most important key data more accessible to a wider audience, nuclide charts have been developed. In this publication, we present the scientific highlights of the new 10th Edition of the Karlsruhe Nuclide Chart.
Fig1epjn The main focus of this Chart is to provide structured, accurate information on the half-lives and decay modes, as well as energies of the emitted radiation for over 4000 experimentally observed ground states and isomer nuclides to an interdisciplinary audience.

World’s oldest periodic table chart found in St Andrews

January 22nd, 2019

A periodic table discovered at the University of St Andrews is thought to be the oldest in the world. Following Menedleev’s famous discovery of periodicity in the chemical elements in 1869, a number of such periodic tables were created. The St. Andrews periodic table is similar to Mendeleev’s second table from 1871. Original_PT2Periodic Table discovered at St. Andrews University, Scotland (Courtesy St. Andrews University).
The United Nations has designated 2019 as the international year of the Periodic Table of chemical elements, recognizing it as an instrument ‘central to linking cultural, economic and political aspects of the global society through a common language’.

Karlsruhe Nuclide Chart (Contour Chart) at URENCO, Netherlands

January 14th, 2019

Nucleonica has arranged the installation of a “contour” version of the Karlsruhe Nuclide Chart at the URENCO premises in Almelo, Netherlands.
The Chart was produced using a 4mm Dibond aluminium plate “cut-out” to fit in a space of height 2m and width 5m and assembled a small distance from the wall. The text is cut from adhesive foil and glued directly on the wall.

Nucleonica Newsletter 2019

January 6th, 2019

Dear Nucleonica Users,
Hopefully you had a great start into the New Year, and we wish you every success in 2019. For the Nucleonica Team, a major focus over the past year was the development and improvement of new and existing applications. Detailed information on these activities is described in this Newsletter.
A highlight in 2018 was the launch of the new 10th Edition of the Karlsruhe Nuclide Chart in early 2018. You can order your copy here.
A further highlight was the development of a new online e-Learning Training Centre, making the Nucleonica product knowledge more transparent and accessible.
NN2019The Nucleonica Team would like to thank you for your continued support.
Best wishes for 2019, Sincerely yours,
Joseph Magill, Managing Director

Nucleonica Training Course, CERN, 16-17 April 2018

April 20th, 2018

Introduction to Nucleonica: Core Applications and Tools, 16-17 April, CERN, Switzerland, 2018.
This 2-day course focused mainly on the Nucleonica core applications with emphasis on Case Studies. A detailed description of nuclear data with particular reference to the various Nucleonica nuclear databases was given. Core applications were demonstrated through the use of the Radiological Converter, Nuclide Mixtures, Decay Engine++, and Dosimetry and Shielding H*(10). The new e-Learning centre to support the Nucleonica applications was described.
IMG_20180416_144805 A key lecture with exercises was given by Mr. Yann Donjoux (CERN) on the e-Ship++ radiological transport assistant application in Nucleonica.
A special session was devoted to gamma spectrometry tools including the Gamma Spectrum Generator, Gamma Library, Cambio and WESPA. The latter tools (Cambio and WESPA) were used for the identification nuclear and radioactive materials.
In total, 11 persons took part in the course from CERN.
Speakers included Mr. Y. Donjoux (CERN) in addition to Dr. J. Magill and Mr. R. Dreher from the Nucleonica team.
