In addition to Ben Crowell's answer: Thorium 229 has a nuclear isomer Thorium 229m that has an energy 8.28±0.17 eV above the ground state. When it decays it does so via an UV wavelength photon (which is a honorary gamma by its origin). As far as I know this is the lowest energy emission known to regularly occur. WebPhoton emission following energy transfer from metastable species to suitable solid targets or to gas targets can be used for metastable detection, but because undirected fluorescence is normally detected with a rather low probability (compared to that for electrons or ions), this approach is less well suited for metastable detection if high sensitivity is needed. remédio zap

WebWhen the electron was raised from the lower energy level to the upper energy level, it had to absorb a photon in order to do this. That photon had an energy equal to the difference in energies of the two levels, that is, an energy of 𝐸 − 𝐸 . When the electron decays back from the upper level to the lower level, the reverse process happens. WebAs the excited molecule returns to ground state, it involves the emission of a photon of lower energy, which corresponds to a longer wavelength, than the absorbed photon. …
