Abstract

Abstract: The isomeric yield ratios of 99m, g Rh, 101m, gg Rh, and 102m, g Rh isomeric pairs produced from the nat Pd(γ, pxn) reactions were measured with the bremsstrahlung end-point energies of 50-, 55-, 60-, 65-, and 70-MeV at the 100 MeV electron linac of the Pohang Accelerator Laboratory, Korea. The measurements were carried out with the activation method in combination with off-line γ-ray spectrometry. In order to improve the accuracy of the activity measurements, the separation of the overlapping γ-rays and the necessary corrections for the counting losses were made. The new experimental results are compared with the theoretical values of the TALYS-1.6 code. Highlights: Measurement of isomeric yield ratios of 99m, g;101m, g;102m, g Rh in the nat Pd(γ, pxn) reactions, The present results measured with the bremsstrahlung end-point energies of 50–70MeV are reported for the first time, The present isomeric yield ratios are compared with the theoretical values using the TALYS-1.6.
