Charge polarization (CP) of fission fragments (FF) has a significant role to decide the yields on the prompt neutron and delayed neutron. To estimate the CP of any FFs, we have investigated the configuration of FF using a microscopic mean-field model. We found that there appears the CP reflected strongly the nuclear structure from the static mean-field calculations. Furthermore, the CPs of light (heavy) FFs can be deduced from the dynamical mean-field model calculation. Their amplitude has been almost consistent with the library data ordinary used.
We have also found that the dynamical model is sensitive to the initial condition, especially for the energy of a system. In this talk, we report the effects of the initial condition with some equal-energy contour on the CP.
