"Hybrid Nuclide Chart in ADOMAH PT format" with ZIP file
n1...@ymail.ne.jp
Hi,
(Because the number of attached PDF files was large, the email did not go through properly. I have now combined nine of the PDFs into a single ZIP file. Please unzip the file to access them. Please excuse me if you receive duplicate emails. Thank you very much for your kind cooperation.)
I have recently completed a project that fuses the periodic table of 118 elements with the nuclide chart of 3,300 isotopes, resulting in what I call the "Hybrid Nuclide Chart in ADOMAH PT format."
In this chart, the ADOMAH PT is divided into seven provisional "strands," arranged in order of atomic number, and placed at the top of the sheet. Below it, I have positioned the nuclide chart.
The nuclide chart is a hybrid format: it combines the IAEA's colour classification of decay modes (2025) with the JAEA's classification of half-life ranges (2018 printed edition), expressed through variations in the width of rectangles. Unlike conventional nuclide charts, the axes are transposed, with the vertical axis representing the number of neutrons.
Please note that I have obtained permission from Mr. Valery Tsimmerman of the United States, the originator of the ADOMAH PT, to use it in this way.

The seven strands form an upward staircase at the points where the electron blocks shift, which I find convenient since the nuclide chart also tends to rise upward.
*Strands and paper sizes
1: 1H–4Be A4 landscape
2: 5B–12Mg A4 landscape
3: 13Al–20Ca A4 landscape
4: 21Sc–38Sr A3 landscape
5: 39Y–56Ba A3 landscape
6: 57La–88Ra Left (57La–70Yb): A3 portrait
Right (71Lu–88Ra): A3 landscape, joined along dotted lines
7: 89Ac–120Ubn Left (89Ac–102No): A3 portrait
Right (103Lr–120Ubn): A3 landscape, joined along dotted lines
When these strands are overlaid to cover the nuclide chart portion, the ADOMAH PT becomes visible. If they are not overlaid but instead connected horizontally in order of atomic number, the result is the hybrid nuclide chart.
Since there is a slight margin between the elements in the nuclide chart, I believe there is room to add further expressions or annotations.
I would appreciate any feedback or comments you may have.
If there is an opportunity, I would be grateful if you could kindly introduce this chart to Professor Y. T. Oganessian.
Best wishes,
Nagayasu

Dear Valery Tsimmerman,
Thank you for your reply.
I believe there are many possible approaches to integrating the PT with the chart of nuclides, but the ADOMAH PT seems to offer a structure that allows such a combination quite naturally.
Just recently, I received an interesting idea from Professor Yoshiteru Maeno of Kyoto University, the creator of "Elementouch." He suggested that, by vertically compressing the nuclide chart and representing each nuclide as a "color‑coded line," it might be possible to display the entire set of nuclides within the periodic table itself. I find this concept appealing, especially because line-based representations can be easily magnified on a PC screen.
I am also considering adding decay pathways, at least for those nuclides used in medical applications such as alpha‑particle targeted therapy (TAT). Arrows work well for representing decay modes, but I am still thinking about how best to depict the radiation emitted during transitions from excited states to the ground state.
As I am not a specialist in nuclear physics, this is quite a challenge for me. Fortunately, recent generative AI tools can explain many of the fundamental concepts in detail, so I have been learning gradually through "conversations" with them.
Sincerely,
Nagayasu
