_diffrn_radiation.polarisn_ratio
Name:_diffrn_radiation.polarisn_ratio
Alias:
_diffrn_radiation_polarisn_ratio
Definition:
Polarisation ratio of the diffraction beam incident on the crystal. It is the ratio of the perpendicularly polarised to the parallel polarised component of the radiation. The perpendicular component forms an angle of _diffrn_radiation.polarisn_norm to the normal to the diffraction plane of the sample (i.e. the plane containing the incident and reflected beams).
