The isomeric yield ratios (IR) of 143m,gSm from the natSm(γ, xn) reaction with the end-point bremsstrahlung energies of 40, 50 and 60 MeV were measured by the activation method and using the 100 MeV electron linac of the Pohang Accelerator Laboratory (PAL), Korea. A high-purity natSm foil in disc shape was used for the irradiation and the induced photo-peak activity of the γ-rays of 143m,gSm in the irradiated sample was measured with a HPGe detector. The experimental data were analyzed through the Gamma Vision program and IR was obtained using a decay equation. The present results are compared with the literature data at other energies. It was found that the IR of 143m,gSm increases sharply from 12 to 20 MeV due to the GDR effect and thereafter remains nearly constant or increases slowly with the end-point bremsstrahlung energy. |
