1 Jun 2011 | | Abstract: | Nuclide production cross sections measured at ITEP for the targets of nat-Cr,
56-Fe, nat-Ni, 93-Nb, 181-Ta, nat-W, nat-Pb, 209-Bi irradiated by protons with
energies from 40 to 2600 MeV were used to estimate the predictive accuracy of
several popular high-energy transport codes. A general agreement of the ITEP
data with the data obtained by other groups, including the numerous GSI data
measured by the inverse kinematics method was found. Simulations of the
measured data were performed with the MCNPX (Bertini and ISABEL options),
CEM03.02, INCL4.2+ABLA, INCL4.5+ABLA07, PHITS, and CASCADE.07 codes. Deviation
factors between the calculated and experimental cross sections have been
estimated for each target and for the whole energy range covered by our
measurements. Two-dimensional diagrams of deviation factor values were produced
for estimating the predictive power of every code for intermediate, not
measured masses of nuclei-targets and bombarding energies of protons. Further
improvements of all tested here codes are recommended. In addition, new
measurements at ITEP of nuclide yields from a 208-Pb target irradiated by 500
MeV protons are presented. A good agreement between these new data and the GSI
measurements obtained by the inverse kinematics method was found | | Source: | arXiv, 1106.0054 | | Services: | Forum | Review | PDF | Favorites | |
