ess.reduce.polarization.he3.he3_opacity_function_from_cell_opacity(opacity0)[source]#

Opacity function for a given cell, based on pressure and cell length.

Note that this can alternatively be defined via neutron beam data, see he3_opacity_function_from_beam_data().

Return type:: He3OpacityFunction[TypeVar(PolarizingElement, polarization.types.Analyzer (str), polarization.types.Polarizer (str))]
