A four-dimensional Langevin model developed in Tokyo Tech has successfully described systematics and anomalies of fission fragment yields and TKEs from actinides to superheavy nuclei. Furthermore, improvement in the fission fragment yield and TKE is confirmed by a method separately calculating fission modes proposed by Brosa and superposing them. In this study, we performed prompt decay calculations with Deterministic Sequential Emission (DSE) model, which calculates sequential neutron evaporations deterministically based on the excitation energy of fragments, using the fission fragment yield and TKE calculated in this method. The DSE model can treat different nuclear temperatures for each fission fragment pair. In the presentation, we will report the prompt fission observables calculated in DSE model and the influence of nuclear temperature on prompt fission observables.
