A new method for determining lattice parameters from powder diffraction patterns of monoclinic crystals

Abstract

AbstractThe parameterβand the squares of the axial ratios are calculated in a first step. These are then used to calculate the parametersa,bandcfrom the angular position of each diffracted line in a series of three very simple and short calculations.The influence of systematic errors and its partial elimination is also considered.All these points are illustrated by an actual case.
