Does a single nucleus in a lattice emit thermal radiation?
If so, how many photons are emitted, one (or more) for each proton? one or more for each proton on same axis? Is the frequency of the photon(s) exactly the number of oscillations per second?
For example, does an atom of golt emit 79 photons ? Consider the oscillation of a nucleus on the z- axis, in what direction travel(s) photon(s)?
The answer excludes the contribution of nuclei in thermal radiation, yet wiki says...
Thermal radiation is a direct result of the random movements of atoms and molecules in matter. Since these atoms and molecules are composed of charged particles (protons and electrons), their movement results in the emission of electromagnetic radiation, which carries energy away from the surface.
...that protons are actively involved. Can anyone explain what produces thermal radiation?
