The electron-phonon interaction for a paramagnetic impurity in an insulating crystal is derived and from that an electron-electron interaction in a higher order is considered. An …
Both the electric-field-gradient (EFG) and mean square displacement (MSD) tensor parameters at the Fe sites in sodium nitroprusside at 23 C have been determined with a high …
Low-temperature anharmonicity plays an important role in ferroelectrics, high-field superconductors, light molecular solids, and other classes of materials of current interest …
Precision measurements of the Mössbauer fractions of Fe 57 in single crystals of Cu, Pd, and Pt were obtained over a range from liquid-helium temperatures to around 750 K in …
Mössbauer results on the absolute resonance strength ln f and on the second-order Doppler shift are found to be approximately linearly related to each other for a variety of systems. This …

Mössbauer parameters, diffusion constants, and coefficients of viscosity for Fe 2+ ions, dissolved from Fe Cl 2· 4 H 2 O, in nominally dry glycerol, glycerol-5-wt% water, and glycerol …

An aluminium based alloy containing 240 ppm of 57Fe in substitution was studied by the Mössbauer effect. The change in the spectrum was followed as a function both of the …

The temperature dependence of Mössbauer parameters (relatively recoil‐free fraction, center shift, and quadrupole splitting) for Fe57 in the NiFe2O4 precipitation process from a …
Mahesh [1] used the Debye model of the vibrational spectra of solid krypton to calculate the recoilless/-factor of the 9.3 keV transition of Kr83m. For this the Mössbauer characteristic …
