摘要

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.
