FISSION PRODUCT YIELDS IN HYBRID (ADS) TARGET MATERIALS INDUCED BY HIGH-ENERGY PROTONS
- and others
Fission product cross sections of (p,f)-reaction in thin samples of {sup 208}Pb, {sup nat}HgO, {sup nat}W irradiated with high-energy protons are measured. The irradiations were made using proton beams extracted from the ITEP synchrotron. The nuclide yields were {gamma}-spectrometered directly using a high-resolution Ge-detector. The GENIE2000 code was used to process the measured {gamma}-spectra and the ITEP-developed SIGMA code was used together with the PCNUDAT nuclear decay database to identify the {gamma}-lines and to determine the cross-sections. The {sup 27}Al(p,x){sup 22}Na reaction was used to monitor the proton flux. The LAHET, CEM2k, CEM95, CASCADE/INPE, CASCADE, INUCL, and YIELDX codes were used for computer simulation of the products measured. Comparison of simulated and experimental values shows insufficient predictive power of the existing fission models. The results obtained are of importance in studying the parameters of the Pb, Hg and W target modules of the hybrid Accelerator-Driven System (ADS) facilities.
