- Аннотация: Hydrides of intermetallic Nb3Me (Me = Au, Ir, Sn) with A15 structure were prepared at hydrogen pressures up to 7 GPa and studied by Mossbauer spectroscopy with the resonances on Au-197 (77.3 keV), Ir-193 (73.0 keV) and Sn-119 (23.9 keV). In all these systems, hydrogenation was found to lead to a reduction in the electron density at the Mossbauer nuclei, but the decrease for Sn-119 was much smaller than for Au-197 and Ir-193. This difference suggests that in Nb3Au and Nb3Ir the hydrogen occupies interstitial sites which are closer to the metal atoms than those occupied in Nb3Sn.
