Isomeric yield ratios for the ^natAg(γ,xn)^{106m,g;104m,g}Ag photonuclear reactions induced by 40-, 45-, 50-, 55-, and 60-MeV bremsstrahlung

We have determined the isomeric yield ratios for the isomeric pairs ^106m,gAg and ^104m,gAg produced on natural silver target nuclei in the bremstrahlung energy region from 40- to 60-MeV. The measurements were carried out by the activation method in combination with direct γ-spectrometry. The necessary corrections were made to improve the accuracy of the experimental results. The present yield ratios measured at 40, 45, 50, 55, and 60 MeV for the ^106m,gAg isomeric pair are 0.019 ± 0.002, 0.022 ± 0.002, 0.023 ± 0.002, 0.025 ± 0.002, and 0.025 ± 0.002, and those for the ^104m,gAg isomeric pair are 1.26 ± 0.12, 1.34 ± 0.12, 1.36 ± 0.12, 1.43 ± 0.12, and 1.49 ± 0.12, respectively. The obtained results are compared with those existing in literature and discussed
