The data governing the interaction of particles with various nuclei or materials
are represented using a multi-group library format specific to the OpenMC code.
The format is described in the MGXS library specification_
The data itself can be prepared via multiple paths including: generation via
NJOY_ and TRANSX_, or directly from a continuous-energy OpenMC calculation by
use of the Python API as is shown in the Python API example_ notebooks. This
multi-group library consists of library meta-data (such as the energy group
structure) and multiple `xsdata` objects which contains the required microscopic
or macroscopic multi-group data.
The format is described in the :ref:`mgxs_lib_spec`.
