Description
In order to study relative yields of 209Bi(γ,xn) reactions, samples of 99.99% pure bismuth-209 were exposed at LINAC-200 electron beam with tungsten convertor at energies 35, 40, 45, 50, 55, 60 MeV. Activities of obtained products of photonuclear reactions with different neutron multiplicity, from (γ,2n) to (γ,7n) were measured. Relative yields normalized to 206Bi yield were calculated. Obtained yields were compared with the experimental results already available in EXFOR database.
Yields obtained by measurements were compared with the results of theoretical calculations and data from public nuclear databases such as IAEA-2019, LEND-99 and TENDL-2021. Bremsstralung spectra and various systematic effects were simulated by GEANT4.
