Depolarized light scattering from monatomic fluids

Abstract

Computer experiments on dense argon are used to evaluate the depolarized spectrum of scattered light. Certain features of the spectrum can be associated with the dynamics of atomic motions in the fluid. The calculations show that the uncorrelated binary collision picture is inadquate since the major time dependence in the variation of the polarizability of the system comes from the correlated reorientation of pairs.
