( Semi Analytical MUons -or taus- Propagation, backwards )

This is a compilation of materials data for the PUMAS library. It contains two type of files:

• Material Description Files (MDF), located under the mdf/elements and mdf/materials directories. These files are coded in XML. The tags specific to MDFs are described in the PUMAS documentation.

  The MDFs provided under mdf/elements are incomplete since they do not define any material. They are provided as samples of atomic element entries.

• Stopping power tables are provided in the dedx directory. These tables have been generated with the PUMAS library. For muons one can also use the tables provided online by the PDG. However, the latter are less accurate than PUMAS ones at high energy due to improvements on the cross-sections of radiative processes (see e.g. Sandrock et al.).

In order to use the MDF with PUMAS please refer to the PUMAS documentation.

The stopping power tables are not needed anymore since PUMAS v1.1. They are self-generated from the MDF at initialisation.

The PUMAS library is under the GNU LGPLv3 license. See the provided LICENSE and COPYING.LESSER files.
