  The work is aimed at experimental determination of the independent and
cumulative yields of radioactive residual nuclei produced in
intermediate-energy proton-irradiated thin targets made of highly isotopic
enriched and natural lead (206,207,208,natPb) and 209Bi. 5972 radioactive
product nuclide yields have been measured in 55 thin targets induced by 0.04,
0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6, and 2.6 GeV protons extracted
from the ITEP U-10 proton synchrotron. 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.
