The 3D Nuclide Chart

The Colourful Nuclide Chart gives easy access to a wide variety of nuclear properties, and allows you to save high quality chart images for publications, presentations and outreach. To navigate the chart just:

Left click and drag to pan.
Right click and drag to rotate.
Scroll to zoom.
Double click to select.

The 3D Nuclide Chart displays data from two evaluations, namely

The Ame2016 atomic mass evaluation
Chinese Physics C41, 030002 (2016)

The Nubase2016 evaluation of nuclear properties
Nucl. Phys. 41, 030001 (2016)

These databases are not reproduced in their entirety, and whilst the data displayed should be correct, no guarantee is given as to the accuracy of the presented information. If mistakes are spotted please let me know. Built using three.js.

Update (2019-05-30)

Added option for background colours (black to white) and transparency.

Update (2019-05-28)

Major update to unified code with 2D version, and implementation of sprite sheet for text renderering. Should now be much faster! So remaining issues when changing fonts on Firefox.

Update (2019-04-29)

  • Updated backend to use common code with 2D version

Update (2018-10-21)


  • Plot as spheres
  • Option to remove isotope labels
  • Configurable shininess

Update (2018-08-22)

First version for testing. Still to do:

  • Improve options stored in cookie
  • Add compass
  • Make key

Quantity to plot


Single [D1(N,Z)] and double [D2(N,Z)] difference modes for quantity V(N,Z) are defined as follows:

D1 = [V(N+dN,Z+dZ)-V(N-dN,Z-dZ)]/2(dZ2+dN2)1/2
D2 = [V(N+dN,Z+dZ)-2V(N,Z)+V(N-dN,Z-dZ)]/2(dZ2+dN2)1/2

where dN and dZ are 0 or 1 in the case of D1 and 2 in the case of D2. The direction of the difference is set by the radio button. These differences approximate the first and second derivatives of quantity V(N,Z). For some introductory discussions on this see:

Custom Colour Points (numeric only)

For more precise control, the mapping between the colour range and the data range can be altered. Below, the first numbers correspond to the point on the define range of colours, and the second number in the text box gives the corresponding fractional point between the minimum and maximum data values.
