str) Optional[Univariate][source]

Get photon energy distribution resulting from the decay of a nuclide

This function relies on data stored in a depletion chain. Before calling it for the first time, you need to ensure that a depletion chain has been specified in openmc.config[‘chain_file’].

New in version 0.13.2.


nuclide (str) – Name of nuclide, e.g., ‘Co58’


Distribution of energies in [eV] of photons emitted from decay, or None if no photon source exists. Note that the probabilities represent intensities, given as [Bq].

Return type

openmc.stats.Univariate or None
