I Photon absorption by electron

  1. Mar 6, 2016 #1
    Can an electron absorb a photon and jump to a higher orbit if the next level is already full of electrons? please explain what happens and also link info that might help me with electron/ photon interaction. I have many questions. Thanks

    It cannot, via the Pauli Exclusion principle and the Fermi-Dirac statistics.
