Detailed Description

G4FPYBiasedLightFragmentDist is an inherited class of G4FissionProductYield that only samples the 'light' fission fragments, defined by A < 115

  • This inherited class of G4FissionProductYield samples only the lighter fission fragments, defined by A < 115
  • This biasing was implemented because of an artifact that is introduced due to random sampling of fission fragments. Typically small fission fragments (neutrons, alphas, gammas) are sampled after the first fragment is sampled. If a heavy fragment (A >= 115) is sampled first then the resulting lighter fission fragment, after all the other particles have been removed from the available mass, will most likely land far off the neutron drip line.
  • This implementation reduces the probability that such an improbable nucleus will be created by first sampling the lighter fission fragment and allowing the heavy fission fragment, which has a lot more flexibility for varying neutron populations, to make up the slack.
