Design of the Decay Chains for Fission Product

  • The evaluation of the half-life and emission rates of delayed neutrons is updated according to the reference library of nuclear science. For uncertain ground states in the fission products, spin designation is carried out using a combination of systematic and theoretical studies and improved data are obtained through corrections. For radionuclides with daughter nuclei in isomeric states, the branching fractions of ground and isomeric states are recalculated with the decay scheme and internal conversion coefficient. Then following a critical review of data in Nuclear Structure and Decay Data File, a special decay database for the design of fission product decay chain is developed. According to the decay law, the complete decay path and information of fission products are established. This work provides a convenient reference for fission product analysis and fission yield research.
