(target_spin, energy_min, energy_max, channel, scattering)[source]¶ Single-level Breit-Wigner resolved resonance formalism data.
Single-level Breit-Wigner resolved resonance data is is identified by LRF=1 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: - 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
- parameters (pandas.DataFrame) – Energies, spins, and resonances widths for each resonance
- q_value (dict) – Q-value to be added to incident particle’s center-of-mass energy to determine the channel energy for use in the penetrability factor. The keys of the dictionary are l-values.
- scattering_radius (dict) – Dictionary whose keys are l-values and values are scattering radii as a function of energy
- target_spin (float) – Intrinsic spin, \(I\), of the target nuclide
