Raman Scattering by Optical Modes of Metals
Raman scattering by the optical modes of the metals Zn, Mg, and Bi has been observed. The measurements were carried out using argon ion laser excitation. One line was observed for each of the hexagonal close packed metals, Zn and Mg, and two lines were observed for Bi. The frequencies that were obtained are: Zn: 70 cm-1, Mg: 120 cm-1, and Bi: 65 cm-1 and 90 cm-1. These frequencies agree reasonably well with neutron scattering data. The temperature dependence of the Raman linewidths are discussed for the above metals.
