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
- Returns
Reich-Moore resonance parameters
- Return type
