Radial distribution functions of the body-centered cubic phase. Two radial distribution functions (RDF) are computed for the system of 1024 Fe atoms using the embedded-atom method (EAM, black solid curve) and the density functional theory (DFT, red dashed curve) at pressure of 360 GPa and temperature of 7000 K (presumably conditions in the center of the inner core). The peaks of the EAM RDF are more distinctive and somewhat displaced in comparison to the DFT RDF. Yet, the similarity is obvious. The heights and positions of peaks of two plots are very close to each other
