openmc.data.ResonanceRange¶
- class openmc.data.ResonanceRange(target_spin, energy_min, energy_max, channel, scattering)[source]¶
Resolved resonance range
- 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
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
scattering_radius (dict) – Dictionary whose keys are l-values and values are scattering radii as a function of energ
target_spin (float) – Intrinsic spin, \(I\), of the target nuclide
- classmethod from_endf(ev, file_obj, items)[source]¶
Create resonance range from an ENDF evaluation.
This factory method is only used when LRU=0, indicating that only a scattering radius appears in MF=2, MT=151. All subclasses of ResonanceRange override this method with their own.
- 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
Resonance range data
- Return type
- reconstruct(energies)[source]¶
Evaluate cross section at specified energies.
- Parameters
energies (float or Iterable of float) – Energies at which the cross section should be evaluated
- Returns
Elastic, capture, and fission cross sections at the specified energies
- Return type
3-tuple of float or numpy.ndarray
