Abstract
The vibrational motion of Sn in the high-critical-field superconductor Sn has been studied with the Mössbauer effect. The Mössbauer thermal shift and recoil-free fraction are found to contain large anharmonic contributions from the soft modes. The soft vibrational motion contributes substantially to the mass enhancement .
