...Major changes and additions to the EGSnrc physics include: option to simulate electron impact ionization, an improved bremsstrahlung data base that includes an exact evaluation of electron-electron bremsstrahlung in the first Born approximation, an improved differential pair production cross section tabulation based on exact PWA calculations that takes into account the asymmetry of the energy distribution at energies close to the threshold, the ability to explicitely simulate triplet interactions (i.e., pair production in the electron field), the ability to take into account radiative corrections for Compton scattering in the one-loop approximation, the ability to use user-supplied atomic and molecular form factors for Rayleigh scattering, and the ability to use total photon cross sections from EPDL97, XCOM, or any other usersupplied tabulation in addition to the default Storm & Israel tabulations....
