Abstract

The isomeric-yield ratios of 109m,gPd and 115m,gCd were measured by the activation method with uncollimated bremsstrahlung beams of 50-, 60-, and 70-MeV generated from an electron linear accelerator at Pohang Accelerator Laboratory. The induced activities in the irradiated foils were measured by the high-resolution γ-ray spectrometric system consisting of a high-purity germanium detector and a multichannel analyzer. The obtained isomeric-yield ratios in the formation of 109m,gPd and 115m,gCd are compared with the corresponding values found in the other experiments and the calculated values based on the statistical model code TALYS. The present results for 109m,gPd and 115m,gCd in this energy region are the first measurement.
