The 57Fe Mössbauer spectrum obtained after 57Mn (T1/2 = 1.45 min) implantation of solid hydrogen was measured at 7 K. The spectrum was analyzed as three components, and the chemical species of each component was assigned from the obtained Mössbauer parameters and the results of density functional theory (DFT) calculations. The formation process of chemical species and the oxidation states of Fe atoms produced by β decay of 57Mn are discussed considering the charge transfer process, in relation to previous emission Mössbauer spectroscopy experiments with 57Co implantation of solid hydrogen at low temperature.
