Query: mudirac: a Dirac equation solver for elemental analysis with muonic
  X-rays   We present a new open source software for the integration of the radial Dirac
equation developed specifically with muonic atoms in mind. The software, called
mudirac, is written in C++ and can be used to predict frequencies and
probabilities of the transitions between levels of the muonic atom. In this
way, it provides an invaluable tool in helping with the interpretation of
muonic X-ray spectra for elemental analysis. We introduce the details of the
algorithms used by the software, show the interpretation of a few example
spectra, and discuss the more complex issues involved with predicting the
intensities of the spectral lines. The software is available publicly at
https://github.com/muon-spectroscopy-computational-project/mudirac.
