excitation energy
editOriginally proposed at Wikidata:Property proposal/Natural science
| Description | energy difference of an excited state from the ground state of its physical system |
|---|---|
| Represents | excitation energy (Q568593) |
| Data type | Quantity |
| Domain | physical system |
| Allowed units | electronvolt (Q83327) |
| Example 1 | nickel-54m (Q108839897) → 6457.4 ± 9 eV[1] |
| Example 2 | Hoyle state (Q27624886) → 7654.07 ± 0.19 eV[2] |
| Example 3 | technetium-99m (Q2373354) → 142.6836 ± 0.0011 eV[3] |
| Example 4 | nickel-54 (Q18845090) → 0 eV |

Motivation
editExcitation 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)
