Nuclide production cross sections measured at the Institute for Theoretical and Experimental Physics (ITEP) for the targets of $$^{rm nat}$$Cr, $$^{56}$$Fe, $$^{rm nat}$$Ni, $$^{93}$$Nb, $$^{181}$$Ta, $$^{rm nat}$$W, $$^{rm nat}$$Pb, and $$^{209}$$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 a number of 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. Further improvements of all tested here codes are recommended. In addition, new measurements at ITEP of nuclide yields from the $$^{208}$$Pb target irradiated by 500-MeV protons are presented.

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. Further improvements of all tested here codes are recommended.

The cross sections for nuclide production in thin $$^{56}$$Fe and $$^{rm nat}$$Cr targets irradiated by 0.04 to 2.6 GeV protons are measured by direct $$gamma$$ spectrometry using two $$gamma$$ spectrometers with the resolutions of 1.8 and 1.7 keV for the $$^{60}$$Co 1332 keV $$gamma$$ line. As a result, 649 yields of radioactive residual product nuclei have been obtained. The $$^{27}$$Al($$p$$, $$x$$)$$^{22}$$Na reaction has been used as a monitor reaction. The experimental data are compared with the MCNPX (BERTINI, ISABEL), CEM03.02, INCL4.2, INCL4.5, PHITS, and CASCADE07 calculations.
