Abstract

Photonuclear excitation of the 103Rh nucleus was studied using synchrotron radiation. Formation of the excited state was confirmed by observing K x-rays emitted following the isomeric transition of 103mRh with a low-energy photon spectrometer. The intensity of induced activity due to 103Rh(γ, γ′)103mRh reaction was determined carefully by subtracting the fluorescent K x-rays due to natural background radiation. The integral cross-section for isomer production of 103mRh by resonance absorption of photons at 295 keV is found to be (2.1 ± 0.8) × 10-28 cm2 eV and is compared with that estimated from the previous experimental value for the 1277-keV level.
