In-beam Mossbauer spectroscopy coupled with a radioactive nuclear beam enables to elucidate the electronic states and reaction products of the isolated iron atoms in gas matrices at low temperatures. The emission Mossbauer spectra of 57Fe obtained after 57Mn implantation into the gas matrices of argon, methane, and ethylene were measured at 18 K. It was found that Monovalent Fe+ with an excited state atomic configuration of 3d7 in the argon matrix, Fe(CH4)2+ species in the methane matrix, and Fe(C2H4) species in ethylene matrix were observed respectively, and assigned on the basis of the obtained Mossbauer parameters and the density functional theory calculations.
