There is a large body of literature, both experimental and theoretical, on collision-induced coherences in atoms, and some of it is almost certain to be relevant to this discussion. See, for a recent theoretical treatment and many references, G. Grynberg and P. R. Berman, Phys. Rev. A 39, 4016 (1989).PLRAAN

For instance, in the model I have presented here, a critical assumption is that the electron current in the discharge tube is treated as, essentially, a stream of classical particles. If, instead, the individual electrons were quantized, one would have to deal with the possibility of entanglement between the electrons and the atoms (as well as with other issues, such as the spreading of the electron wave packet). Entanglement, in particular, would destroy the atomic coherence if the energy of the incoming electron is more sharply defined than the few eV of a typical optical transition. It can be argued that this would not generally be the case in a high-voltage discharge tube, but this shows the kinds of difficulties a first-principles calculation would have to face
