Dickfore: Your request puts me back to where I was when I logged into "free particle spectrum" For starters check out http://farside.ph.utexas.edu/teaching/jk1/lectures//node85.html. Next google "free electron laser" and "Absorption spectra of electrons in plasmas". There are a lot of...

(Bob S and Dickfore):Wow. But light does interact with an electron. It does get polarized-angular momentum gets exchanged.Why can't the electron gain mass along with the energy, or lose angular momentum, at least temporarily.

Thank you, Bob S. I appreciated the references to Thomson Scattering. I'll try to track down all the scattering processes. I feel certain that scatter is the result of an energy absorption process for the electron and an exchange of energy &/or momentum by the photon...

Thank you,alxm. But I was hoping for an answer a bit more detailed than was found in the existing threads. Can you refer to a calculation- say one showing the transition dipole is not zero, or some experimental observation,like the electron population between the Earth and sun diminishes the...

I was tracking down your thread "free particle spectrum" and others on google, but found nothing specific . Has no one calculated/measured it yet? I can imagine the experiment: a discharge tube, say a meter long with transparent electrodes maintaining a 1 amp current flow at a variable...
