Is photon emission possible without electrons changing energy levels?

Yeah. Of course it could be an electron or a positron or anything charged.
In that case yes indeed. The atom changes energy level and spin and emitts a photon :)
But isnt that just an example of subjecting the atom to an external field. So it is another way of exciting the system ie putting energy in. Like what is mentioned above in the post.
Thanks for the reply.
