Abstract

Raman spectra of Be were studied at room temperature at pressures up to 23 GPa. The transverse-optical (TO) zone-centre phonon mode of hcp Be could be observed to maximum pressure. Neither new modes nor anomalies in the pressure shift were observed in the pressure range of 8.6-14.5 GPa where a phase transition has been reported. The TO mode frequency and its pressure dependence are discussed in terms of the elastic properties of Be.
