The muon energy loss equation (at high energies) is:(adsbygoogle = window.adsbygoogle || []).push({});

-dE/dx = a(E) + b(E)E

where a(E) represents the ionization losses (Bethe equation), and b(E) represents radiative losses (bremsstrahlung, pair production, photo-nuclear).

From what I have read, at high energies for high-Z materials, radiative losses dominate ionization losses (beyond the muon critical energy). I am ok with the ionization part but is there a simple way to represent the radiative losses (b(E)E) for a certain Z or density?

I can't seem to find anything, even though on the graphs you see of energy loss v. energy, the radiative losses seem to pretty much follow a straight line.
