Description
We have added the multipole humped fission barriers model into the Unified Hauser-Feshbach and Exciton Model for Fission Nuclei (FUNF). With the help of the MINUIT, we optimized the parameters of FUNF to reproduce the cross-section of neutron-induced $^{238}U$. The double-humped fission barrier can be used to explain the low energy resonance structure of $n+^{238}U$ fission cross-section at low energy.
