Detailed Description

Unique standard model particle identifiers by the Particle Data Group.

This namespace acts an enumeration for PDG codes that are used by the various processes in Celeritas. (Unlike an enumeration, though, PDG codes can be arbitary and aren't limited to the ones defined below.) They should be extended as needed when new particle types are used by processes.

PDG numbers between 81 and 100 are reserved for internal use. The table shows which internal arbitrary numbers are currently defined:

Particle name	PDG
Generic ion	90
