Assume for simplicity that dE/dx = (dE/dx)min/B² = C/B². Prove that the range of a particle of initial energy Eo = myo is R = mc² (yo - 1)²/(Cyo). Find the range of a muon in iron (C = 1.48 MeV cm² g¯¹) for initial momentum between 0.1 GeV/c and 1 TeV/c. Do the same for a proton. Compare with the curves in the Review of Particle Physics.
