Abstract

We present neutron scattering measurements on low energy phonons from a superconducting (Tc 2.7 K) Sn0.8In0.2Te Single crystal sample. The longitudinal and a transverse acoustic phonon modes have been mapped out around the (002) Bragg peak for temperatures from 1.7 K to 10 K. There is no clear anomaly in hte phonon excitations, including intensities, energies and peak widths below or above Tc. In addition, we confirm that the compound is well ordered, with no significant diffuse scattering or superstructure.
