TALYS is a nuclear-reaction program that simulates nuclear reactions with the Hauser-Feshbach statistical decay theory.
We applied Hauser-Feshbach statistical decay theory that incorporates TALYS to the de-excitation of fission fragments. The characteristics of fission fragments, Y(Z, A, Eex, Jπ) that is used as inputs of TALYS calculation, were imported from several models.
In our series of presentations, (1) we describe Y(Z, A, Eex, Jπ) distributions and the method that TALYS calculates the de-excitation of fission fragments. The simultaneously calculated independent fission product yields and other fission observables up to 5 MeV incident neutron energies were compared with experimental and evaluated data.
