High-Energy Threshold Reaction Rates on 0.8 GeV Proton-Irradiated Thick   W and W-Na Targets
  Threshold activation reaction rates in 12C, 19F, 27Al, 59Co, 63Cu, 65Cu, 64Zn, 93Nb, 115In, 169Tm, 181Ta, 197Au, and 209Bi experimental samples placed along the axis inside and outside the 0.8 GeV proton-irradiated 92-cm thick W-Na and 4-cm thick W targets where measured at the ITEP proton synchrotron. 158 reactions of up to +AH4-0.5 GeV thresholds have been measured in 123 activation samples for W-Na target, and 157 reactions in 36 activation samples for W target. The reaction rates were determined using the gamma-spectrometry method. In total, more than 1000 values of activation reactions were determined in the experiments. In both cases the measured reaction rates were compared with the LAHET code simulated rates and using several nuclear databases for the respective excitation functions, namely, ENDF/B6 for cross section of neutrons at energies below 20 MeV and MENDL2 together with MENDL2P for cross sections of protons and neutrons of 20 to 100 MeV energies. A general satisfactory agreement between simulated and experimental data has been found.
