0030 // Description: model for electron and positron interaction with nuclei
0031 //              using the equivalent photon spectrum.  A real gamma is
0032 //              produced from the virtual photon spectrum and is then
0033 //              interacted hadronically by the Bertini cascade at low
0034 //              energies.  At high energies the gamma is converted to a
0035 //              pi0 and interacted with the FTFP model.
