The xraylib library for X-ray–matter interactions. Recent developments

This work presents the recent developments of xraylib, an ANSI C library that provides convenient access to a large number of X-ray related databases, with a focus on quantitative X-ray fluorescence applications. The enhancements include improved X-ray fluorescence production cross sections that take into account cascade effects and M-lines, as well as revised line energies, atomic level widths, Compton broadening profiles etc. A full overview of the complete application programming interface is presented.

► Xraylib is a library for X-ray–matter interactions useful for XRF applications.
► Xraylib has recently been updated with many new features.
► The complete application programming interface is presented.
► Xraylib is released under the open source BSD license and can be obtained from github.
