InteractionCrossSections#

class MCEq.data.InteractionCrossSections(mceq_hdf_db, interaction_model='DPMJETIII193')[source]#

Bases: object

Class for managing the dictionary of hadron-air cross-sections.

Parameters:

  • mceq_hdf_db (object) – instance of MCEq.data.HDF5Backend

  • interaction_model (str) – name of the interaction model

Methods Documentation

get_cs(parent, mbarn=False)[source]#

Returns production parent-air cross-section \(\sigma_{prod}^{proj-Air}(E)\) as vector spanned over the energy grid.

Parameters:

  • parent (int) – PDG ID of parent particle

  • mbarn (bool,optional) – if True, the units of the cross-section will be \(mbarn\), else \(\text{cm}^2\)

Returns:

cross-section in \(mbarn\) or \(\text{cm}^2\)

Return type:

numpy.array
