Research on natAg(γ,xn)103-106Ag reaction cross sections with the bremsstrahlung end-point energy of 70 and 75 MeV

초록

The flux -weighted average cross sections ofnatAg(gamma,xn)103-106Ag reactions were measured with the bremsstrahlung end -point energy of 70 and 75 MeV using an activation and off-line gamma-ray spectrometric technique. The GEANT4 code was used for the simulation of the bremsstrahlung spectra. The cross sections of natAg(gamma,xn) 103106Ag reactions as a function of mono -energetic photons were theoretically calculated by using the TALYS-1.96 code. The data of the present work and literature at different bremsstrahlung end -point energy are found to be in agreement with the theoretical values within the uncertainty limit. It can be seen that the flux -weighted average cross sections of the natAg(gamma,xn)105.106Ag reactions increase with bremsstrahlung energy up to the Giant Dipole Resonance region. Thereafter, a small decrease trend with the bremsstrahlung energy was seen due to the opening of another reaction channel.
