Measurement and simulation of the cross sections for the production of Gd-148 in thin W-nat and Ta-181 targets irradiated with 0.4- to 2.6-GeV protons

The cross sections for the production of Gd-148 in W-nat and Ta-181 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 alpha 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.
