Abstract

A method for solving the phase problem ab initio in crystal structure studies by neutron diffraction bee11 suggested. This method is based on the anomalous scattering of thermal neutrons by certain nuclei. using the data collected at two neutron energies, the process of phase determination is carried out in two steps: (i) the location of the position of the anomalous scatterer and (ii) the correlation of the phase of the structure factor with the phase of the anomalous scatterer The method gives unique solution of the phases. The expressions deduced arc general and can he used for X-ray anomalous scattering also.13; 13;
