ess.spectroscopy.indirect.kf.final_wavenumber(sample_analyzer_vector, analyzer_detector_vector, analyzer_dspacing)[source]#

Find the wave number of the neutrons reflected to each detector-element.

The wave number and wavelength are inversely proportional with

\[\text{wavelength} = 2 * \pi / \text{wavenumber}\]
Parameters:

  • sample_analyzer_vector (Variable) – The vector from the sample to the analyzer interaction point for each detector element.

  • analyzer_detector_vector (Variable) – The vector from the analyzer interaction point to its detector element, for each detector element.

  • analyzer_dspacing (Variable) – The lattice plane spacing of the analyzer crystal.

Returns:

Variable – The magnitude of the reflected neutron wave vector for each detector element.
