Description

Conversion electron Moessbauer spectra of 73.0 keV γ-rays from iridium 193Ir were obtained at liquid helium temperature by detecting low-energy electrons emitted from the resonant iridium absorber with a channel electron multiplier. This new technique analyzes iridium within a depth of about 1 μm from the surface of materials, with a sensitivity several times greater than in conventional Moessbauer transmission measurements. A resonant effect of up to 10% has been observed for thin metallic iridium and IrO2 films having natural isotopic composition. (orig.)
