Test calculations of photoneutrons emission from surface of uranium sphere irradiated by 28 MeV electrons

In this paper the results of physical verification for the BOFOD photonuclear data files are reported, available for the uranium isotopes U sup 2 sup 3 sup 5 , U sup 2 sup 3 sup 8. These results were compared with calculated data by the parameterization driven model of photonuclear reaction and experimental data. Experimental data of photoneutron yields from surface of uranium sphere irradiated by 28 MeV electrons are used for a verification. Both calculations have been carried out with the RTS and T general purpose Monte Carlo code with detailed electron-photon-nucleon transport simulation using the ENDF/B-VI and EPDL evaluated data libraries.
