ReichMoore
(target_spin, energy_min, energy_max, channel, scattering)[source]¶ ReichMoore resolved resonance formalism data.
ReichMoore resolved resonance data is identified by LRF=3 in the ENDF6 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 lvalues and values are channel radii as a function of energy
 scattering (dict) – Dictionary whose keys are lvalues 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 lvalue. Note that this may be different than the value for the evaluation as a whole.
 channel_radius (dict) – Dictionary whose keys are lvalues 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 lvalues which must be used to converge the calculation
 scattering_radius (dict) – Dictionary whose keys are lvalues 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 ReichMoore resonance data from an ENDF evaluation.
Parameters:  ev (openmc.data.endf.Evaluation) – ENDF evaluation
 file_obj (filelike 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: ReichMoore resonance parameters
