Measurements are reported for optical phonons (k = 0) by Raman scattering at 300, 80, and 2 I ( for Bi, Cd, Mg, and Zn. The linewidths are found to increase, and the frequencies t~ decrease, as the temperature is raised. The temperature dependent portion of the linewidth is attributed t o a two-phonon decay process. In addition, the contributions to the linewidth from the isotope effect, the electron-phonon interaction, and strains are disoussed.
