Excitation functions of product nuclei from 40 to 2600 MeV proton-irradiated 206,207,208,natPb and 209Bi

5972 nuclide yields from proton-irradiated 206,207,208,natPb and 209Bi thin targets have been measured for 11 proton energies within the range 0.04–2.6 GeV. The measured data have been compared with data obtained at other laboratories as well as with theoretical simulations by seven codes. We found that the predictive power of the tested codes is different but is satisfactory for most of the nuclides in the spallation region, though none of the codes agree well with the data in the whole mass region of product nuclides and all should be improved further.
