# Can a light element with excited nucleus undergo internal conversion?

Internal conversion occurs when an excited nucleus ejects a low level electron from the first 2 low energy shells such as a $$k$$-shell electron instead of emitting gamma when returning to ground state. Normally this is associated with heavy elements as the low level electron wave function is more likely to come under the influence of the nucleus.

Can this also occur for light elements such as Lithium, Beryllium, Boron etc? Particularly if they are in a suitably excited state.

If so, can a valence electron from the 2nd shell be emitted directly by internal conversion?

If so what would happen if that valence electron is being used in a molecular or crystal bond?

A) would the internal conversion be inhibited?

B) would the valence electron be emitted?

C) would the kinetic energy instead be distributed between the different atoms in the bond and cause the bond to vibrate or break?

Note that for heavier elements where the electron affected by internal conversion is not directly the valence electron, I suppose the valence electron would be ejected normally. There would then be different indirect effects as the electrons rearrange themselves to the lower energy level possibly with auger photon emission. This would also then affect the valence electron indirectly. I'm also curious on what would happen with heavy atoms due to the loss of valence electron this way but mainly interested in what happens with light atoms with valence electrons directly affected by internal conversion.
