MCNP6 updated proton-induced fission cross section calculations at intermediate energies

MCNP6 has been Validated and Verified against intermediate-and high-energy fission crosssection experimental data. Recent improvements contained in CEM03.03F and MCNP6-F to consider precompound emission of heavy clusters up to Mg-28 has necessitated a re-calculation of fission cross sections. With our re-calculation, we find that CEM03.03F, which is used in MCNP6-F, predicts fission cross sections in good agreement with available experimental data for reactions induced by protons on both subactinide and actinide nuclei at incident energies from several tens of MeV to several GeV.
