Experimental data were used to calculate the absorption spectrum of a monolayer, the effective scattering, absorption, and extinction coefficients. The optical properties of a single granule were theoretically obtained with Mie theory for the homogeneous and two-layered spheres with regard to size-dependence of Cu optical constants in the frame of the model of a mean free path electron limitation [Pg.175]

Now, let us look at Fig. 13. Here, the static structure factor of a three-dimensional homogeneous suspension of polystyrene spheres of diameter 94 nm is shown. The particles volume fraction is 0 = 2.0 x 10 4. Experimental data from static light scattering (closed circles) are compared with computer simulation (Monte Carlo) results (symbol x) and theoretical predictions (lines) obtained from the Ornstein-Zernike equation and different closure relations. The computer simulations and the theoretical calculations where carried out assuming that the interaction between the [Pg.25]
