Abstract

The ⁵⁷Fe Mössbauer spectrum obtained after ⁵⁷Mn (T_1/2 = 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.
