particle¶
Collection of data structures and functions for particle information.
This module defines a particle as a collection of quantum numbers and things related to this.

load_particles
(filename: str) → None[source]¶ Add entries to the particle database from a custom config file.
By default, the expert system loads the particle database from the XML file
particle_list.yml
that comes with theexpertsystem
. Use this function to append or overwrite definitions in the particle database.Note
If a particle name in the loaded XML file already exists in the particle database, the one in the particle database will be overwritten.
