Partial structure correlations in amorphous Ni 83La 17

Abstract

Short range order in amorphous Ni 83La 17 was examined by neutron and X-ray diffraction. The two experimental total pair correlation functions (TPCF) were used as input data for model calculations. Computer modelling was based on a new method using the molecular dynamic (MD) technique and the Born–Green–Bogoljubov (BGB) equation (without superposition approximation). All three PPCF, atomic first neighbour angle distributions, Voronoy polyhedra (VP) distributions and other structure properties were derived.
