Abstract

We measured nuclear forward scattering spectra utilizing the ${}^{99}{Ru}$ transition, 89.571(3) keV, with a notably mixed $E 2 / M 1$ multipolarity. The extension of the standard evaluation routines to include mixed multipolarity allows us to extract electric and magnetic hyperfine interactions from ${}^{99}{Ru}$ -containing compounds. This paves the way for several other high-energy Mössbauer transitions, $E \sim 90 keV$ . The high energy of such transitions allows for operando nuclear forward scattering studies in real devices.
