On Mossbauer dynamics in Nb3Sn
Nuclear Research Laboratory, Bhabha Atomic Research Centre, Trombay, Mumbai 400 085, India
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.
