Abstract
We have observed, by means of Raman studies at elevated temperatures, strong anharmonic interactions between one-phonon states and between one- and two-phonon states in aluminum phosphate. These result in striking destructive interference of scattering amplitudes and in the formation of coupled modes. Hybridization of one- and two-phonon states is compared with that observed in quartz.Keywords
