GSAS (Generalized Structure Analysis System)

GSAS (Generalized Structure Analysis System) is a software tool used by scientists to analyze data from techniques like X-ray and neutron diffraction, which reveal the arrangement of atoms in a material. It helps researchers determine the precise 3D structure of crystals by fitting theoretical models to the experimental data, accounting for factors like atomic positions, vibrations, and defects. GSAS streamlines the process of structural refinement, enabling accurate interpretation of material properties and guiding the development of new materials in fields such as chemistry, physics, and materials science.
