摘要：

The X-ray absorption fine structure of crystalline selenium under pressure from 0 to 10 GPa was studied. The pressure dependence of the first, second and third neighbor distances was determined by a curve fit analysis. The mean square displacement of the first peak increased with increasing pressure while that of the second peak decreased. These changes are attributed to the weakening of the covalent bond and the strengthening of the interchain interaction.
