Description
We measured isomeric cross-section ratios for the 45Sc , (γ,n)44m,gSc ,gSc, natTi,x)44m,gSc,103Rh ,4n)99m,gRh, and natFe, x)52m,gMn reactions at the 65-MeV electron linac of the Pohang Accelerator Laborator by using the activation method. Samples of natural Sc, Ti, Rh, and Fe metallic foils were irradiated in an uncollimated bremsstrahlung beam. The isomeric crosssection ratios were determined from the activity measurement with a high-purity germanium detector. The measured isomeric ratios were 0.21 ± 0.03, 0.12 ± 0.03, 1.43 ± 0.20, and 0.28 ± 0.04 for the 45Sc ,(γ,n)44m,gSc, ,gSc, natTi ,x)44m,gSc, 103Rh ,4n)99m,gRh, and natFe ,x)52m,gMn reactions, respectively. The present results for the 45Sc ,(γ,n)44m,gSc,gSc and natFe ,x)52m,gMn reactions are in good agreement with other measurements. The present results for natTi ,x)44m,gSc and 103Rh ,4n)99m,gRh reactions are the first such measurements.
