The effect of the interatomic distances distribution character on the radial distribution function of amorphous solids

Abstract

It is proposed parabolic assignment of the radial distribution function peaks shape. It is shown that this assignment is more in line with the real structure of disordered atomic networks, in comparison with the Gauss distribution. At the same time its application more adequately describes also the partial struc­tural factors in diffraction studies of the amorphous solids. The analysis shows that the description of co­ordination spheres atomic networks of amorphous substances bу parabolic distribution functions can sig­nificantly improve the resolution of the radial distribution function method.
