Abstract.

We compare the anharmonic Lamb Mossbauer factor and the q-Lamb Mossbauer factor by studying the anharmonicity observed in the f-factor data of Nb₃Sn. We also show that this anharmonicity does not arise due to the presence of potential.

Keywords.:Anharmonicity; lattice dynamics; Mossbauer spectroscopy; superconductor.
