From preceding figure:

Figure 3. The isomer of Lutecium decays to the ground state of hafnium by two different paths. The isomeric decay mode occurs 21.7% of the time with a 10 unique gamma lines. The beta decay mode occurs 78.3% of the time with 40 gamma lines and one beta energy

[tau ~ 160.4 d for 177mLu, 6.68 d for 177Lu]

This physics image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Lutetium nuclear isomer energy levels.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
