What wave modes make gamma rays?

Gamma rays typically have frequencies above 10 exahertz (or >10¹⁹ Hz), and therefore have energies above 100 keV and wavelengths less than 10 picometers (less than the diameter of an atom).

I doubt they are electro magnetic if they are shorter than the atomic radius. How would they be quantized to EM levels if that were so? The wave mode is most likely nuclear/electro. They would make mass in our gravity field, their wave length so short they would be captured with the Null density we have. These are of the same intensity as gluons, in fact, they are gluons coupled to charge in free space. They carry a large group of Nulls.  Higgs, according to my last reading, are simply wave loaded with free Null, they don't get far before the wave becomes quark and gluon. So these gamma rays should be the highest frequency of wave sustainable in neutral free space.

So, just get the relative quantization ratio between electro wave and the gluon, compute the space impedance relative to speed of light, and you have it. The logic here is that if we strip the atom of electron kinetic energy, then the remaining balance of phase is based simply on electron charge, so we get nuclear/electro wave mode.  If the atom emits, then th4e residual, stable magnetic field in the region would have some quantization value relative to total electron energy. Its a tricky subject and I need work on separating out energy levels, but being a simple counter of things, I need more things I count.
