Photon and electron
WebIt's a two eV photon because the electron dropped two electron volts in energy, and now that the electron's at the four eV energy level, it'll fall back down to the ground state, emitting a four eV photon in the process. So electrons will sometimes drop multiple energy levels at a time, and sometimes they'll choose to take individual steps, but ... WebDec 7, 2024 · The intention of this Special Issue on electron and photon interactions with (bio) molecules is to bring together different areas of knowledge that focus on radiation interactions with matter. Photon interactions play an important role, since biological tissue is consistently exposed to photon radiation. It is known that high-energy radiation ...
