We applied the Hauser-Feshbach statistical decay theory to the excited fission fragments formed just after fission to calculate the fission product yield, and the prompt fission neutron and gamma-ray spectra. In this study, we forcus on the fission product yield and the isomeric ratio. The calculated independent yield were compared by the nuclear data and the experimental data. The isomeric ratios of various fission products were calculated and compared by the simple assumption model introduced by Madland and England. The energy dependence of the fission product yield and the isomeric ratio were also studied.
