X-RAY REFLECTOMETRY AND SMALL-ANGLE SCATT ERING

Using a Monte Carlo method, a numerical computing of the scatterring b y a set of spheres is made. The spheres are randomly distributed in a half space The aim of the study is to justify or to reject the assumpt ions which could be supposed to interpret the experimental results of specular reflectivity of cermets. Cermets are metallic clusters embedd ed in ceramic matrix. The extrapolation of numerical results allows us to think that layers of cermet behave like homogeneous stacks in firs t approximation.
