Description:
IC-POWLS is a modified version of the Computer program POWLS (POWder Least Squares) for calculation and refinement of crystallographic and magnetic structures from powder diffraction data. POWLS comprises the calculation of structure model intensities for X-ray or neutron powder diffraction. The program uses integrated intensities of individual reflections or groups of overlapping reflections as observed quantities to adjust the model parameters in a non-diagonal weighted least squares procedure. IC-POWLS has been extended for the analysis of neutron diffraction data to be simultaneously analysed for crystallographic andcommensurate or incommensurate magnetic structures. The program is written in Fortran-77 and is designed to run on IBM mainframe computers, on VAX maschines or on IBM compatible personal computers.
