Correlated atomic motions in glassy selenium

Description

The elastic and total (energy-integrated) structure factors for glassy selenium have been measured by means of neutron spectroscopy within the temperature range 15 KT310 K. The correlated nature of the atomic vibrations gives rise to marked features in the total (energy-integrated) inelastic structure factors defined as the difference between the total and elastic intensities. Also, both structure factors show rather distinct dependences with temperature, which are discussed in some detail.
