In this work, Zr, I, Pr, Au and Pb photoneutron reaction cross sections were calculated by using TALYS 1.6 computer code near the peak of the giant dipole resonance. The calculated results were compared with the measured values available in the literature. Similarities and discrepancies among previous studies were discussedAbstract: : In this work, Zr, I, Pr, Au and Pb photoneutron reaction cross sections were calculated by using TALYS 1.6 computer code near the peak of the giant dipole resonance.
