The docs said “The cross sections are in scaled form” in openmc.data.IncidentPhoton. It it means that I have to make it divided by a $(\beta^2/Z^2)E_k$ to get a real cross section? Why it is designed in this complex way to perfrom?
@skyair The bremsstrahlung cross section data come from a 1986 paper by Seltzer and Berger. The scaling that you mention is just how they appear in the tabulations from that paper.
