A Mossbauer-effect study of iron cobalt titanium hydride

Abstract
The intermetallic compound Fe0.5Co0.5Ti and its hydride phases Fe0.5Co0.5TiHx were investigated through transmission Mossbauer spectroscopy in the composition range 00.5Co0.5Ti and the alpha -phase hydride are single lines with identical widths and isomer shifts, and the beta -phase spectrum is a quadrupole doublet. Any spectrum for a mixture of phases can be resolved as a sum of a single line and a quadrupole doublet; the relative spectral area of each component is proportional to the concentration of the phase to which the component corresponds. The Mossbauer parameters in the beta -phase can be explained in terms of the expansion and distortion of the lattice without having to introduce a direct effect arising from the hydrogen.
