Hi,


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.


Thank you.


Best wishes,

Nagayasu
