openmc.data.ArbitraryTabulated

class openmc.data.ArbitraryTabulated(energy, pdf)[source]

Arbitrary tabulated function given in ENDF MF=5, LF=1 represented as

\[f(E \rightarrow E') = g(E \rightarrow E') \]

Parameters:

energy (numpy.ndarray) – Array of incident neutron energies
pdf (list of openmc.data.Tabulated1D) – Tabulated outgoing energy distribution probability density functions

Variables:

energy (numpy.ndarray) – Array of incident neutron energies
pdf (list of openmc.data.Tabulated1D) – Tabulated outgoing energy distribution probability density functions

classmethod from_endf(file_obj, params)[source]

Generate arbitrary tabulated distribution from an ENDF evaluation

Parameters:

file_obj (file-like object) – ENDF file positioned at the start of a section for an energy distribution.
params (list) – List of parameters at the start of the energy distribution that includes the LF value indicating what type of energy distribution is present.

Returns:

Arbitrary tabulated distribution

Return type:

openmc.data.ArbitraryTabulated
