Formula for scattering and energy change of photons on (naked) nuclei

What is the formula for scattering and energy change of photons on (naked) nuclei?

(On wikipedia Compton scattering does only explain scattering of photons by electrons, and I'm not even aware if the scattering with atomic nuclei has a different name, I always assumed it would be Compton scattering, too.)

This is a followup from X-ray shielding .
