Abstract

Mössbauer emission spectroscopy performed with ⁵⁷Co implanted in solid hydrogen reveals a single quadrupole-split component assigned to an FeH molecule. This molecular bond is characterized by a temperature-independent quadrupole splitting ΔE_Q of 2.4 (1) mm/s and an isomer shift with respect to α-Fe of 0.59(5) mm/s. The FeH is formed following dissociation of the H₂ molecule due to the highly energetic electron-capture, decay process. The molecule persists at least up to 70 K, long after evaporation of the H₂ matrix. These results are discussed in connection with previous attempts to observe the formation of FeH by conventional rare-gas-matrix isolation.
