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 ΔEQ 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.
