GetFissionProduct()

G4Ions * G4FPYNormalFragmentDist::GetFissionProduct ( void  )

protectedvirtual

Selects a fission product from the probability tree, limited by the number of nucleons available to the system.

Implements G4FissionProductYieldDist.

    // Generate a (0, 1] random number and return the respective particle.
    // The ENDF data tables lists 72172 as the largest fission fragment produced
    // for any fission event. The maximum alpha production is 10 and the
    // smallest fissile isotope is 90227. This means that if isotope 72172 were
    // selected as the first daughter product, then at 10 alpha particles only
    // 15 nucleons and -2 protons would remain for the second daughter product.
    // Although the actual probability of this occurring is very small, or 0 in
    // this case, a check should still be made to ensure that the second
    // daughter product can be physically realized. This would prevent a
    // situation such as this extreme example which results in a nucleus of 13
    // neutrons and 2 anti-protons.
    // This quick sanity check may become even more valid if the ENDF data
    // tables are expanded in the future and include larger fission products.
