# openmc.data.ReichMoore¶

class openmc.data.ReichMoore(target_spin, energy_min, energy_max, channel, scattering)[source]

Reich-Moore resolved resonance formalism data.

Reich-Moore resolved resonance data is identified by LRF=3 in the ENDF-6 format.

Parameters
• target_spin (float) – Intrinsic spin, $$I$$, of the target nuclide

• energy_min (float) – Minimum energy of the resolved resonance range in eV

• energy_max (float) – Maximum energy of the resolved resonance range in eV

• channel (dict) – Dictionary whose keys are l-values and values are channel radii as a function of energy

• scattering (dict) – Dictionary whose keys are l-values and values are scattering radii as a function of energy

Variables
• angle_distribution (bool) – Indicate whether parameters can be used to compute angular distributions

• atomic_weight_ratio (float) – Atomic weight ratio of the target nuclide given as a function of l-value. Note that this may be different than the value for the evaluation as a whole.

• channel_radius (dict) – Dictionary whose keys are l-values and values are channel radii as a function of energy

• energy_max (float) – Maximum energy of the resolved resonance range in eV

• energy_min (float) – Minimum energy of the resolved resonance range in eV

• num_l_convergence (int) – Number of l-values which must be used to converge the calculation

• scattering_radius (dict) – Dictionary whose keys are l-values and values are scattering radii as a function of energy

• parameters (pandas.DataFrame) – Energies, spins, and resonances widths for each resonance

• target_spin (float) – Intrinsic spin, $$I$$, of the target nuclide

classmethod from_endf(ev, file_obj, items)[source]

Create Reich-Moore resonance data from an ENDF evaluation.

Parameters
• ev (openmc.data.endf.Evaluation) – ENDF evaluation

• file_obj (file-like object) – ENDF file positioned at the second record of a resonance range subsection in MF=2, MT=151

• items (list) – Items from the CONT record at the start of the resonance range subsection
