摘要

We measured nuclear forward scattering spectra utilizing the Ru-99 transition, 89.571(3) keV, with a notably mixed E2/M1 multipolarity. The extension of the standard evaluation routines to include mixed multipolarity allows us to extract electric and magnetic hyperfine interactions from Ru-99-containing compounds. This paves the way for several other high-energy Mossbauer transitions, E similar to 90 keV. The high energy of such transitions allows for operando nuclear forward scattering studies in real devices.
