Measurement and simulation of the cross sections for nuclide production in W-nat and Ta-181 targets irradiated with 0.04- to 2.6-GeV protons

The cross sections for nuclide production in thin (nat)Wand Ta-181 targets irradiated by 0.04-2.6-GeV protons have been measured by direct gamma spectrometry using two gamma spectrometers with the resolutions of 1.8 and 1.7 keV in the Co-60 1332-keV gamma line. As a result, 1895 yields of radioactive residual product nuclei have been obtained. The Al-27(p, x)Na-22 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.
