 Description of energy losses of charged particles in matter
 
-This paper describes improvements to the GEANT3 muon dEdX, which is used also in CORSIKA7: [1-s2.0-S016890020001007X-main.pdf](uploads/0a07e54410651947544636fac5b772c2/1-s2.0-S016890020001007X-main.pdf) The effects are only important for the >multi TeV region and concern radiative losses. A lot of cross sections are specified in the paper. 
+The 2018 edition of the Review on Particle Properties describes the Bethe formula for energy losses and we use this as baseline:

+This is determined to order Z^{2} by quantum calculation.

+Sternheimer's approximation (R.M. Sternheimer, Phys. Rev. 88, 851 (1952)) for the high energy density corrections are also described in the RPP.
