RESUMO

The different manifestations of the crystalline potential anharmonicity in GaSe were studied. The temperature dependence of one and multiphonon mode energies was obtained from infrared absorption and Raman scattering experiments. The temperature and frequency dependence of multiphonon absorption coefficient were discussed.
