Inner shell electrons

  1. Apr 3, 2005 #1
    Is it possible to excite the inner shell electrons to higher energy state? If not, why not? I'm aware of selection rules for atomic transitions and haven't come across anything that would indicate that those transitionss are forbidden

    Yes, it is. Core-level photoemissions do just that. Same with Auger spectroscopy.

    The reason why they are "rare" comes directly from the Fermi Golden Rule. The probability of the transition goes like a matrix element divided by the difference in energies.
