2026-05-22 Associated Data for "Theory and Experiment Study of the 3D DuMond Diagram in X-ray Backscattering" doi:10.57760/sciencedb.35651 en This dataset includes experimental raw data that supports the core conclusions of the paper. The publicly available measured data is mainly based on experimental measurements, which is sufficient to support the independent verification of experimental reproduction and the core conclusions of the paper. The dataset contains two types of experimental measurement data: 1、 Projection of Backscatter 3D DuMond Diagram on the Θ - Φ Plane Corresponding folders' 0meV ',' -200meV ', and' 400meV 'correspond to X-ray energy deviating from backscattering energy by 0 meV, -200 meV, and+400 meV, respectively. Each folder contains swing curve data for each angle, with file names corresponding to different angles. The data file is in ASCII text format (. dat), which can be imported using Origin software or opened directly with a text editor. Each file contains three columns: the first column is the scanning angle, with a step size of 200/arcsec; The second column is a blank column; The third column shows the intensity values recorded by the photodiode detector. 2、 Projection of Backscatter 3D DuMond Diagram on the Δ E - Θ Plane The corresponding folder "E-theta" contains swing curve data for various energies. The file names in the folder correspond to energy deviation values, such as "-0.3" indicating that the X-ray energy deviates from the backscattered energy by -0.3 eV. The data file format is the same as above.  3D DuMond diagram; X-ray backscattering; theory and experiment ke wan zhen Si Shangyu XUE Lian LI Zhongliang PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.7498/aps.75.20260088 Science Data Bank
