_diffrn_radiation.polarisn_ratio
Name:'_diffrn_radiation.polarisn_ratio'
Definition:
Polarization ratio of the diffraction beam incident on the crystal. This is the ratio of the perpendicularly polarized to the parallel-polarized 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).
