Detailed Description

Calculate differential cross sections for relativistic bremsstrahlung.

This accounts for the LPM effect if the option is enabled and the electron energy is high enough.

The screening function uses Tsai's analytical approximations of coherent and incoherent screening function to the numerical screening functions computed using the Thomas-Fermi model (tsai-1974) .

Note

This is currently used only as a shape function for rejection, so as long as the resulting cross section is scaled by the maximum value the units do not matter.
