Motivation
[edit]Excitation energy is a key quantity to describe metastable state of nuclides in nuclear physics. This concept is also present in an atomic electron systems, molecule, potential field or solid-state electron or phonon system but I did not find any item to apply this quantity to other domains of physics.

- Support I thought we had pretty good coverage of properties for isotopes, but yes it looks like this one was missed (and could be applicable elsewhere also). ArthurPSmith (talk) 14:38, 11 October 2021 (UTC)
- Support Clearly needed. /ℇsquilo 09:29, 12 October 2021 (UTC)
- Support There is tons of physical property to add, thanks for it. --Thibdx (talk) 20:27, 13 October 2021 (UTC)
