Microwave Emissions And Chromium239

Would microwave emissions that come in contact with chromium 239 kick out free electrons in the sense that lower order electrons become excited and release a electron for other particle use? If so, if you had a usable draw for it, could you use chromium 239 as a solid state battery? Of course the Chromium 239 would bond with adjacent atoms, but if the atoms were exterior for replenishment and vacuumed internally to capture is it a possibility?

Definitely!

If there were such an isotope of Chromium. Duck Dodgers and the Martian used it all up in that episode, unfortunately.

Oops, hard of the ears and that really didn't make sense. Atomic number 238 Uranium 92 would be the correct one I was thinking of.

No microwaves are not ionizing radiation and cannot eject electrons from isolated atoms. In bulk uranium metal, you can develop currents in the electrons which are already free in the conduction band, but that's a different phenomenon. The lower electrons are more tightly bound to the atom than the higher shells, so you would need strong x-rays to eject them, not microwaves. Also, since the atomic number and not the atomic mass controls how electrons are bound to the atom, the exact isotope does not matter.

This still holds for such an extreme case (X against microwave). But for over 10 years, experiments see green or infrared laser light ionize atmospheric nitrogen, despite not having the minimum photon energy, just because this light is concentrated over time and volume.

In this case, theorists say "multi-photon absorption" and avoid to detail it.
In the case of non-linear crystals doubling or tripling laser frequency, people say "non-linear" and avoid to put quantum vocabulary on it.

But we shouldn't conceal this is a serious departure from what we were taught about QM few years ago.

And I wish someone would reformulate QM in a way that includes multi-photon effects. My hope is that such a formulation would give better insight than now of the processes, not only at electrons absorbing photons, but of what is an interaction.
