Abstract
Samples made from natural bismuth were exposed in 60 MeV end-point bremsstrahlung beam. In this paper, a simple model for determination the share of two ways of 203Pb formation: by the decay of 203Bi, produced in 209Bi(γ,6n)203Bi reaction and by 209Bi(γ,p 5n)203Pb reaction is described. The method employs the ratio of 203Pb and 203Bi nuclei numbers and activities at the end of the exposure as the input value. This ratio was estimated from gamma spectra measured after irradiation of natural Bi sample. It was found that the rate of production of 203Pb by 209Bi(γ,p 5n)203Pb reaction is about 6% of the 203Bi production rate in the 209Bi(γ,6n)203Bi reaction. Obtained result is compared with TALYS based estimation.
