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.
