Description
Activation yields of 209Bi(p, xn)207,206,205,204,203Po, and 209Bi(p, pxn) 207,206,205,204,203Bi reactions were measured up to 100 MeV to verify the Monte Carlo codes, FLUKA, MARS, and PHITS. In addition, the gap in the excitation functions of abovementioned radio-nuclei was filled. The target was arranged in a stack consisting of Bi, Al, Au foils and Pb plates. The proton beam intensity was determined by activation analysis method using 27Al(p, 3pn)24Na, 197Au(p, pn)196Au, and 197Au(p, p3n)194Au monitor reactions in parallel as well as Gafchromic film dosimetry method. The activities of produced radio-nuclei in the foils were measured by HPGe spectroscopy system. A good agreement was observed between the present experimental data and the previously published data. The ratios of the results of calculations by the codes to the measured activation yields of Po radio-nuclei did not exceed 1.3 over the whole beam range. In the case of Bi radio-nuclei, ratios were less than 1.4 except for 204Bi radionuclide of which was 2.3. In conclusion, a satisfactory agreement was observed between the present experimental data and the simulations.
