EVALUATION OF NEUTRON PRODUCTION CROSS SECTIONS AND EMISSION SPECTRA IN THE PROTON-INDUCED REACTION OF C-12, FE-56, AND PB-208 UP TO 250 MEV

In the particle transport analysis of the target system of ADS, proton-induced nuclear data, especially neutron yields and neutron emission spectra, play a key role. In this paper, as part of KAERI high energy library task, we present evaluation of (p;xn) doubledierential neutron emission spectra for C-12, Fe-56, and Pb-208 for energies up to 250 MeV which are important nuclear data in the ADS target.
