Excite Inner Shell Electrons: Can It Be Done?

In summary, it is possible to excite inner shell electrons to higher energy states through core-level photoemissions and Auger spectroscopy. However, these transitions are rare due to the Fermi Golden Rule, which states that the probability of the transition decreases with the difference in energies.

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.
