Abstract : The structure of amorphous red phosphorus has been studied by neutron diffraction, using both reactor and pulsed neutron sources. Real-space pair correlation functions obtained by Fourier transformation of the experimental scattering data have been compared with those calculated for a three-fold coordinated CRN model, which had been energy-relaxed using a combination of bonding and non-bonding interatomic potentials. Only moderate agreement between theory and experiment was found. The discrepancies are ascribed to the presence of a considerable degree of intermediate-range order in the amorphous solid, in particular consisting of cage-like clusters characteristic of the monoclinic Hittorf form of phosphorus.
