openmc.data.ProbabilityTables(energy, table, interpolation, inelastic_flag=-1, absorption_flag=-1, multiply_smooth=False)[source]¶ Unresolved resonance region probability tables.
Parameters: - energy (Iterable of float) – Energies in eV at which probability tables exist
- table (numpy.ndarray) – Probability tables for each energy. This array is of shape (N, 6, M) where N is the number of energies and M is the number of bands. The second dimension indicates whether the value is for the cumulative probability (0), total (1), elastic (2), fission (3), \((n,\gamma)\) (4), or heating number (5).
- interpolation ({2, 5}) – Interpolation scheme between tables
- inelastic_flag (int) – A value less than zero indicates that the inelastic cross section is zero within the unresolved energy range. A value greater than zero indicates the MT number for a reaction whose cross section is to be used in the unresolved range.
- absorption_flag (int) – A value less than zero indicates that the “other absorption” cross section is zero within the unresolved energy range. A value greater than zero indicates the MT number for a reaction whose cross section is to be used in the unresolved range.
- multiply_smooth (bool) – Indicate whether probability table values are cross sections (False) or whether they must be multiply by the corresponding “smooth” cross sections (True).
