Usually, it is necessary to convert these raw, instrument-specific, data into a quantity; the double differential scattering cross section, that largely depends on the physics of the sample under investigation, as described in Sec.

The neutron scattering cross section is about a factor of 20 higher for the ortho configuration compared to the para configuration.
Since cold neutrons will depolarize in a liquid deuterium target in which the scattering cross section is much larger than the absorption cross section, it will be necessary to quantify the loss of polarization before capture.
