Description
Summary:This work explores and describes the possibility of assessment of high energy bremsstrahlung spectrum, through the use of photonuclear reactions. Experimentally obtained values of saturation activities of various Bi isotopes, created by 209Bi(γ, xn) reactions in the 100 MeV bremsstrahlung beam were used in calculations. The photon spectrum is obtained by utilizing the unfolding techniques and cross sections data calculated by the TALYS 1.96 code. The experimental results were compared with the results obtained by Geant4 Monte Carlo simulation. •Unfolding methods can reliably well construct bremsstrahlung spectrum.•Only basic theoretical assumptions about the shape of the spectrum are required.•Unfolding results agree reasonably well with Monte Carlo simulations.
