X-ray Reference Data in SQLite library, including a Python interface.
The repository contains useful data about the intereactions of X-rays with matter. It packages these different data sources into a single sqlite3 database which can, in principle, be used by a very large number of computer programming languages and environments.
The data and code here are placed in the Public Domain.
A web interface using XrayDB to display X-ray properties of the elements can be found at https://millenia.cars.aps.anl.gov/xraydb/ and https://xraydb.xrayabsorption.org/
The code for this web interface is at https://github.com/xraypy/xrayweb
The X-ray Scattering data from the Elam Tables was modified from code originally written by Darren S. Dale.
Refined values for anomalous scattering factors have been provided directly by Christopher T. Chantler.
The project has mostly been supported and maintained by Matt Newville. Suggestions and conributions are most welcome.
This project has moved around a bit. Originally part of Larch (https://xraypy.github.io/xraylarch/), and then part of Scikit-Beam (https://github.com/scikit-beam/scikit-beam), the XrayDB now has a permanent home here at (https://github.com/xraypy/XrayDB).
