Abstract: The results of experimental and computer simulation studies of the yields of residual product nuclei in Bi-209 thin targets irradiated by 130 MeV and 1.5 GeV protons are presented. The yields were measured by direct high-precision gamma-spectrometry. The gamma-spectrometer resolution was 1.8 keV in the 1332 keV line. The gamma-spectra were processed by the ASPRO code. The gamma-lines were identified, and the cross sections defined, by the SIGMA code using the GDISP radioactive database. The process was monitored by the Al-27(p,x)Na-24 reaction. Results are presented for comparisons between the 209-Bi(p,x) reaction yields obtained experimentally and simulated by the HETC, GNASH, LAHET, INUCL, CEM95, CASCADE, and ALICE codes.
