Karlsruhe Nuclide Chart Online (KNCO++) Revisited

August 22nd, 2017

The Karlsruhe Nuclide Chart Online (KNCO++) has been upgraded to provide the following new features:
– The colours used in the KNCO++ have been historically based on the modes of decay. A new colour scheme has been introduced which shows, in addition, the half-lives of the nuclides. The user can toggle between the decay modes and half-lives charts to obtain the complimentary Chart views.
KNCO_BG2Karlsruhe Nuclide Chart Online, KNCO++, with new features.
– The user can now select various pre-defined background colours to enhance the visual impact of the Chart.
– When the mouse cursor is placed over a nuclide, the nuclide box is highlighted and magnified (see example of U-238 above). On clicking on the highlighted nuclide, the Chart is zoomed to the nuclide selected thus provided a useful navigation tool.
– Literature references for the nuclide data are now availabe. A mouse right click on a nuclide opens a context menu from which a link to the references can be selected.

Karlsruhe Nuclide Chart Online – Literature references now available

May 31st, 2017

Following user requests, the Karlsruhe Nuclide Chart Online (KNCO) has now been updated to provide the literature references for the nuclide chart updates in the various editions. This allows users to trace the literature references used in the nuclide data evaluation process.Pt196In the example above the references for Pt 196 are shown. From the KNCO, the nuclide Pt 196 is selected. Using the right mouse click, a Show References link leads to the latest references for this nuclide also shown above. The references are subdivided according to the edition (e.g. 10th, 9th, 8th). For each edition the entries are arranged according to Spin and Parity, Half-life, Radiations/Decay Modes, and Cross-sections.

Obituary Gerda Pfennig, 8.12.1930 – 16.2.2017

March 1st, 2017

Gerda Pfennig, “Mother” of the Karlsruhe Nuclide Chart, died on 16 February 2017 aged 86.
GerdaPfennigBorn on 8 Dec. 1930, Gerda Pfennig received her training in chemistry at the Fachschule Fresenius, Wiesbaden. In 1958, she joined the Institut für Radiochemie (Institute of Radiochemistry) of the Kernreaktor Bau- und Betriebsgesellschaft mbH (Nuclear Reactor Building and Operating Company) in Karlsruhe. The first edition of the Karlsruhe Nuclide Chart, printed in 1958 in the form of a wall chart, was created by Walter Seelmann-Eggebert and his assistant Gerda Pfennig. Since this first edition, Frau Pfennig has co-authored all editions of the Chart until the 9th Edition in 2015. During the period 2006-2012 Frau Pfennig was working at the European Commission’s Institute for Transuranium Elements on the 7th (2006) and 8th (2012) editions of the Chart. From 2012-2015 she was actively involved with Nucleonica GmbH on the 9th edition of the Chart. Her life was marked with a passion for music, tennis and the nuclide chart.
In the field of nuclear data Frau Pfennig was both conscientious and dedicated and an inspiration to her colleagues. We will always keep her in our memories.

Reduced Decay Schemes

February 23rd, 2017

The Reduced Decay Schemes is a new application for displaying the reduced decay schemes of selected nuclides.
The nuclear data contained in the nuclide boxes (in the Karlsruhe Nuclide Chart for example) is concise due to the very limited space available. In order to obtain maximum benefit from the nuclide chart, it is important to know how to interpret the box contents correctly. In the new application, the contents of the nuclide boxes are explained in detail by making reference to the nuclide reduced decay scheme in order to relate the box contents with information on energies of emitted particles with the energy levels in the nucleus in the decay scheme diagram. Additional data has been taken from the Nuclear Data Sheets and Nucleonica’s Datasheets.
RDS_K42 To improve understanding, some transitions not mentioned in the box are added and indicated as dotted lines. Corresponding data is also indicated in grey. Radiations with a low emission probability indicated by dots or brackets in the nuclide box are also drawn with dotted lines.
Additionally a gamma spectrum of the particular nuclide is shown (generated by Nucleonica’s Gamma Spectrum Generator application).

Nucleonica Newsletter 2017

January 3rd, 2017

Dear Nucleonica Users,
In 2016, we continued with our mission to build the most innovative technical resource for knowledge creation & competence preservation for the worldwide nuclear science community. Our vision is to provide scientists, engineers and technical personnel in the field the best software solutions and, in addition, create a sustainable home for the nuclear science community on the web.
Nucleonica Online Applications:
During the past year, we have again extensively upgraded and re-written a wide range of applications. In particular the following new applications have been created: Photon Dose Rate Constants, Radiological Converter, and Dosimetry & Shielding, H*(10). Pages 2-4 describe these new developments in more detail.
nn_2017Nucleonica Dedicated Training Courses:
In the area of training, 2016 has been a busy year for the Nucleonica team. In May there was a 2-day training course in CERN. This was followed by 3 training courses at the WAK / KIT in Karlsruhe and a course at JEN mbH on the Fz-Juelich site. In November, a training course was held at the BfS premises in Berlin with emphasis on nuclear security and nuclear material identification. For more information see pages 11-13.
If you would like to book a dedicated training course for your organisation 2017, please make sure to register your interest as soon as possible. To enquire about Nucleonica training courses, please send an email to info@nucleonica.com.
Karlsruhe Nuclide Chart:
We continue to provide updates to the Karlsruhe Nuclide Chart through a collaboration with the EC’s DG Joint Research Centre. The new element names recently accepted by IUPAC have been included in the Karlsruhe Nuclide Chart Online. To order copies of the most recent version of the Chart, please place your order here. More information can be found on page 10.
We Welcome your Feedback:
Finally, thanks to all our partners and users for the many suggestions and proposals which we received during 2016. Many of these have been discussed in our Forum and where possible the relevant application has been updated. A particular example here was the request to update the Dosimetry & Shielding and related applications to include the internationally standarised ambient dose equivalent H*(10).

On the following pages, this Newsletter informs you in more detail about the above developments. Hopefully you find this of interest.
Finally, thanks for your continued support and best wishes for 2017.
Sincerely yours,
Joseph Magill
Managing Director

Names proposed for chemical elements 113 (Nh), 115 (Mc), 117 (Ts), 118 (Og)

June 9th, 2016

They are nihonium (with the symbol Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og). Until now, the quartet have been referred to simply by the number of protons in each atom – 113, 115, 117 and 118, respectively. The new names and symbols have been updated in the Karlsruhe Nuclide Chart.
Newelements2Excerpt from the Karlsruhe Nuclide Chart, showing the location of the recently named nuclides (Elements 113, 115, 117, and 118).
Nihonium references the Japanese name for Japan. The atom 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 including the one that will now bear his name.
