openmc.data.AngleDistribution¶

class openmc.data.AngleDistribution(energy, mu)[source]¶

Angle distribution as a function of incoming energy

Parameters

energy (Iterable of float) – Incoming energies in eV at which distributions exist
mu (Iterable of openmc.stats.Univariate) – Distribution of scattering cosines corresponding to each incoming energy

Variables

energy (Iterable of float) – Incoming energies in eV at which distributions exist
mu (Iterable of openmc.stats.Univariate) – Distribution of scattering cosines corresponding to each incoming energy
