The work is aimed at experimental determining and computer simulating the independent and cumulative yields of residual product nuclei in the target and structure materials of the transmutation facilities driven by high-current accelerators. The ITEP U-10 accelerator was used in 48 experiments to obtain more than 4000 values of the yields of radioactive residual product nuclei in 0.1-2.

Abstract-The cross sections for nuclide production in thin nat W and 181 Ta targets irradiated by 0.04-2.6-GeV protons have been measured by direct γ spectrometry using two γ spectrometers with the resolutions of 1.8 and 1.7 keV in the 60 Co 1332-keV γ line. As a result, 1895 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 have been compared with the MCNPX (BERTINI, ISABEL), CEM03.02, INCL4.2, INCL4.5, PHITS, and CASCADE07 calculations.

Pb target irradiated by 500MeV protons are presented. A good agreement between these new data and the GSI measurements obtained by the inverse kinematics method was found.

Abstract-The cross sections for the production of148 Gd in nat W and 181 Ta targets irradiated by 0.4-, 0.6-, 0.8-, 1.2-, 1.6-, and 2.6-GeV protons at the ITEP accelerator complex have been measured by direct α spectrometry without chemical separation. The experimental data have been compared with the data obtained at other laboratories and with the theoretical simulations of the yields on the basis of the BERTINI, ISABEL, CEM03.02, INCL4.2, INCL4.5, CASCADE07, and PHITS codes.

Abstract-The cross sections for nuclide production in thin93 Nb and nat Ni targets irradiated by 0.04-to 2.6-GeV protons have been measured by direct γ spectrometry using two γ spectrometers with the resolutions of 1.8 and 1.7 keV in the 60 Co 1332-keV γ line. As a result, 1112 yields of radioactive residual nuclei have been obtained. The 27 Al(p, x) 22 Na reaction has been used as a monitor reaction. The experimental data have been compared with the MCNPX (BERTINI, ISABEL), CEM03.02, INCL4.2, INCL4.5, PHITS, and CASCADE07 calculations.

The results of experimental and computer simulation studies of the yields of residual product nuclei in 209 Bi thin targets irradiated by 130 MeV and 1.5 GeV protons are presented. The yields were measured by direct high-precision γ-spectrometry. The γ-spectrometer resolution was 1.8 keV in the 1332 keV line. The γ-spectra were processed by the ASPRO code. The γ-lines were identified, and the cross sections defined, by the SIGMA code using the GDISP radioactive database. The process was monitored by the 27 Al(p,x) 24 Na reaction. Results are presented for comparisons between the 209 Bi(p,x) reaction yields obtained experimentally and simulated by the HETC, GNASH, LAHET, INUCL, CEM95, CASCADE, and ALICE codes.
