Detection of nonequilibrium phonons by means of resonance Raman scattering (RS) of light
Maksimov A. A., Tartakovskii A. A.
A method is proposed for optical detection of nonequilibrium acoustic phonons by means of resonance Raman scattering of light. The ballistic-propagation velocities of acoustic phonons along the a and b axes of an anthracene crystal are determined experimentally.
