openmc.data.DiscretePhoton¶

class openmc.data.DiscretePhoton(primary_flag, energy, atomic_weight_ratio)[source]¶

Discrete photon energy distribution

Parameters:	primary_flag (int) – Indicator of whether the photon is a primary or non-primary photon. energy (float) – Photon energy (if lp==0 or lp==1) or binding energy (if lp==2). atomic_weight_ratio (float) – Atomic weight ratio of the target nuclide responsible for the emitted particle
Variables:	primary_flag (int) – Indicator of whether the photon is a primary or non-primary photon. energy (float) – Photon energy (if lp==0 or lp==1) or binding energy (if lp==2). atomic_weight_ratio (float) – Atomic weight ratio of the target nuclide responsible for the emitted particle
