Le Bail method

The Le Bail method is a technique used in the field of crystallography, specifically in the analysis of X-ray or neutron diffraction data for determining the crystal structure of materials. It is particularly useful when the crystal structure is not fully known or when dealing with complex structures. The core idea of the Le Bail method is to perform a profile fitting of the entire diffraction pattern, rather than relying on the traditional method of indexing peaks from the diffraction pattern and then refining the structure.
