openmc.data.decay_photon_energy

openmc.data.decay_photon_energy(nuclide: str) → Univariate | None

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’].

Added in version 0.13.2.

Parameters:

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

Returns:

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/atom] (in other words, decay constants).

Return type:

openmc.stats.Univariate or None
