Pre-neutron-emission mass distributions for reaction238U(n, f) up to 60 MeV

  • The pre-neutron-emission mass distributions for reaction 238U(n, f) up to 60 MeV are systematically studied with an empirical fission potential model. The energy dependence of the peaks and valleys of the pre-neutron-emission mass distributions is described by an exponential form based on the newly measured data. The energy dependence of evaporation neutrons before scission is also considered, which plays a crucial role in the reasonable description of the mass distributions. The measured data of the pre-neutron-emission mass distributions for reaction 238U(n, f) are reasonably well reproduced up to 60 MeV. The mass distributions at unmeasured energies are also predicted using this approach.

Pre-neutron-emission mass distributions for reaction238U(n, f) up to 60 MeV

    Corresponding author: SUN Xiao-Jun,

Abstract: The pre-neutron-emission mass distributions for reaction 238U(n, f) up to 60 MeV are systematically studied with an empirical fission potential model. The energy dependence of the peaks and valleys of the pre-neutron-emission mass distributions is described by an exponential form based on the newly measured data. The energy dependence of evaporation neutrons before scission is also considered, which plays a crucial role in the reasonable description of the mass distributions. The measured data of the pre-neutron-emission mass distributions for reaction 238U(n, f) are reasonably well reproduced up to 60 MeV. The mass distributions at unmeasured energies are also predicted using this approach.
