Residual nuclide formation in 206,207,208,nat-Pb and 209-Bi induced by 0.04-2.6 GeV Protons as well as in 56-Fe induced by 0.3-2.6 GeV Protons

摘要

5972 independent and cumulative yields of radioactive residuals nuclei havebeen measured in 55 thin 206,207,208,nat-Pb and 209-Bi targets irradiated by0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6, and 2.6 GeV protons.Besides, 219 yields have been measured in 0.3, 0.5, 0.75, 1.0, 1.5, and 2.6 GeVproton-irradiated 56-Fe target. The protons were extracted from the ITEP U-10synchrotron. The measured data are compared with experimental results obtainedelsewhere and with theoretical calculations by LAHET, MCNPX, CEM03, LAQGSM03,CASCADE, CASCADO, and LAHETO codes. The predictive power was found to bedifferent for each of the codes tested, but was satisfactory on the whole inthe case of spallation products. At the same time, none of the codes cande-scribe well the product yields throughout the whole product mass range, andall codes must be further improved.
