    Mössbauer Spectroscopy — Nuclear Gamma Resonance

    The chemical and structural properties of an atom can be studied from the shifts and degeneracy of its nuclear energy levels. These changes in the nuclear state are easily observed by using the resonance spect...

    NGR study of IrSn4 and Ir3Sn7 intermetallic compounds in external magnetic fields

    An interpretation for spectra of IrSn4 and Ir3Sn7 obtained in external magnetic fields is proposed. The trigonal IrSn4 exhibits asymmetric spectrum without external magnetic field. By application of magnetic fiel...

    On the occurrence and role of SnO2, SnS and FeSn2 in coal hydroliquefaction experiments using tin-based catalysts

    Mössbauer Spectroscopy, X-Ray Diffraction and Electron Microscopy were applied to the study of solid residues of coal hydroliquefaction, for which tin-based catalysts were used. In the general case hydroliquef...

    An attempt to use Mössbauer spectroscopy in studies of coking similarity of Western Canadian cretaceous and appalachian carboniferous coals

    Western Canadian cretaceous coal (WC5) and Appalachian carboniferous coal (AC4) are good coking coals, although their rheological properties predict a different behaviour with this respect. According to Mössba...
