Vp. Voloshin et Yi. Naberukhin, ON THE ORIGIN OF THE SPLITTING OF THE 2ND MAXIMUM IN THE RADIAL-DISTRIBUTION FUNCTION OF AMORPHOUS SOLIDS, Journal of structural chemistry, 38(1), 1997, pp. 62-70
The splitting of the second maximum of the radial distribution functio
n of an irregular atomic packing is regarded as an indication of the a
morphous state of a substance. This paper describes the splitting-form
ing atomic configurations using Delaunay simplices, representing chain
s of elementary configurations. It is shown that the splitting is form
ed of chains in which all simplices are nearly regular tetrahedra and
quartoctahedra.
