/** G4FPYBiasedLightFragmentDist is an inherited class of G4FissionProductYield
43
* that only samples the 'light' fission fragments, defined by A < 115
44
* - This inherited class of G4FissionProductYield samples only the lighter
45
* fission fragments, defined by A < 115
46
* - This biasing was implemented because of an artifact that is introduced
47
* due to random sampling of fission fragments. Typically small fission
48
* fragments (neutrons, alphas, gammas) are sampled after the first
49
* fragment is sampled. If a heavy fragment (A >= 115) is sampled first
50
* then the resulting lighter fission fragment, after all the other
51
* particles have been removed from the available mass, will most likely
52
* land far off the neutron drip line.
53
* - This implementation reduces the probability that such an improbable
54
* nucleus will be created by first sampling the lighter fission fragment
55
* and allowing the heavy fission fragment, which has a lot more
56
* flexibility for varying neutron populations, to make up the slack.
