This is a rare example of the electronic world influencing the nuclear
world.

If gamma-/x-ray bombardment is being investigated for charging up
nucleonic energy states, then could the subtlety of electronic spin
states be used as a a more elegant release trigger for the energy in a
nuclear isomer?
