Abstract
We report Raman scattering measurements on the ${E}_{\mathrm{g}}$ (${{\ensuremath{\Gamma}}_{12}}^{+}$) optical phonon measured from 50-340 K on a single crystal of ${\mathrm{V}}_{3}$Si. This phonon line has an anomalous width, shape, and temperature dependence, suggesting direct coupling between the phonon and electronic excitations.
